Does it matter if boys like cars, and girls like dolls? Both genders will love anything specifically tailored to them

We often make the case that men and women are naturally different by citing the fact that boys overwhelmingly love toy cars, and that girls prefer dolls. But is it possible that this is the result of trial-and-error by toy-makers? "Ah-hah!" the toy maker said to themselves, "I found a toy that boys consistently love." Perhaps boys and girls only share slight differences in their preference for amusements, and it's just that popular gendered toys dominate the marketplace.

Gender is not defined by mass marketability. Just because there are some signal products that most women want exclusively, such as lipstick, doesn't mean all male-female differences are signal. The differences could just be the loudest signals in the market which have drowned out all other data.

Every sex cultivates an attractive trait well before the opposite sex has had a chance to know what's happening

When women say they dress more for other women than for men, it's because they're playing a bigger game than men can understand. In the grand scheme of things, the fashion of one sex is meant to appeal to the other sex, but men can only appreciate a sliver of the fashion acumen of women. Women want to be ahead of limited apparent male taste and appeal to man's subconscious tastes. Hence, women instead compete to be the most fetching of the fetchers. They depend on each other to create beauty contests and assess each other's skills, rewarding each other's fashion sense with status, but ultimately they are competing in those same contests.

Likewise, men too are bonded by elaborate rituals to sort each other out. Women may never know the convoluted adventures men partake in to create novel and abundant professional and creative successes. If a man only has a few minutes to convince a woman whether or not to mate with him, that man will seek all of the advantages he can get. Are the men who run Fortune 500 companies doing so to impress women? Perhaps in the grand scheme of things, but that thought isn't what gets those CEOs up in the morning or allows them to tolerate a boring meeting. It's a sense of mission or intrinsic reward that motivates them. For if someone is driven just by the minimum needed to impress a member of the opposite sex, their genes would likely be out-duplicated by someone willing to impress the already minimally impressive.

Half of all genetic traits are latent

Mom's needlework is present in her, but obscured in her sons. Likewise her sons' ambitions may be muted in their daughters. For the muted recipients, those traits either remain completely dormant, or find some narrow or redirected expression, either through proxy hopes and dreams or more gender-appropriate ones.

Homosexuality advances in times of peace

Homophobia among men is a choice made by the group when the costs of sexual tension outweigh the benefits of sexual abandon. The main cost is jealousy, which leads to disunity, which in the case of the military, could be fatal, but is probably less important now that we conduct war using video gamers and supply chain experts.

The benefits of sexual abandon are social. When people have sex, they bond through the exercise of shared pleasure. As a result, homosexuality advances in times of peace, when social networking is more important than either marital or martial focus. If Steven Pinker's prediction in Why Violence Has Declined comes true, then we are returning to a more liberal era, similar to the Ottomon's, the Weimar's, or even the Ancient Greek's, when homosexuality was as banal metrosexuality.

Homosexuality exists because sex is useful

Start from there, and then it's easy to sketch the rest of its evolution.

How can homosexuality be a choice if people need to be "cured" from it?

Conservatives often resist gay marriage on the belief that homosexuality is a choice. And yet, those same opponents suggest that gays and lesbians should seek ex-gay therapy. But if homosexuality is a choice, it shouldn't require therapy to correct. If someone has to be "cured" of homosexuality, then the "victim" of homosexuality is as blameless as someone who needs to be cured of cancer.

If human evolution is the evolution of choice, then birth control is progress, giving us the option to reverse the irreversible

One of the most commonly cited cases of humans subverting evolution is birth control. Those who want to reconfigure notions of masculinity and femininity justify it by the unprecedented amount of freedom that birth control has given women.

But is it a safe assumption that the pill is a radical departure from evolutionary struggles? Birth control has existed forever in one sense, in the form of infertility. It has also existed after the evolution of choice in the form of abstinence. And it has existed in crude medical ways for many millennia. Evolution wants both strategies. On the one hand, it wants reproduction to spread like wildfire, with people having sex and multiplying with abandon. On the other hand, it wants, if necessary, calibrated control.

Just as evolution gave us the choice to subvert urges when necessary, it also gave us technology-making skills to put those choices into effect.

Technically, procreation is pointless since its only purpose is itself, which means genitals don't need a purpose either

Robert R. Reilly makes the case against gay marriage by citing the principle of entelechy, which states that the purpose of things inheres in the design of those things. One can look at the design of a man and the design of a woman, and see that they are clearly built for procreating. But can the principle of entelechy address the bigger design question: What is the purpose of procreation?

Procreation produces creatures that are a genetic mix of their parents to attempt new and better ways of surviving in the world. But the attempt to create newer and better ways of surviving doesn't have a purpose. It's not trying to create a more perfect human. Rather, procreation is an end in of itself. It is simply to be. If the ultimate ends are pointless, then in a way, the subordinate ends are too.

There are masculine versions of feminine things men are attracted to and vice-versa

So, for example, a woman who is soft translates into a man who is sensitive. Or a man who is powerful translates into a woman who is confident.

To say that the purpose of genitalia is inherent in the design of it is to deny the other 99 uses of it

Entelechy, or the principle that the purpose of things inheres in the design of things, leads to a tyranny of the majority. People have to agree to the purpose and the design of something, and therefore the most popular opinion prevails. If one takes a pluralistic view, that everything has multiple purposes and multiple designs, then minority uses of the human body, such as the homosexuality, wouldn't be suppressed.

While homophobia has become passé, a non-bigoted resistance to homosexuality may emerge in its place

Conservatives will lick their wounds from legal setbacks on gay marriage and likely adapt the messaging of their values. While homophobia is becoming increasingly passé, a non-bigoted resistance to homosexuality might emerge in its place. The suppression of homosexuality is an ancient battle, and motivated parents will continue producing environments that discourage homosexuality. Homosexuality could wind up classified as an adult topic or not family-friendly, something that children should be shielded from. "Out and proud" might be replaced with modesty. Privacy could become a larger part of the gay conversation. Currently, right-wing libertarians justify lifting legal restrictions on homosexuality less because "gay is okay" but more to "get the government out of the bedroom."

Some members of the gay community may ultimately aid in the new obscurity. Pride was necessary to counteract the notion that homosexuality was bad, evil, or illegal. But once the legal victories have been checked off, the revolutionary justification for emphasizing acceptance may weaken as well.

Women transmit class, men acquire it

All the class signals seem to be the mainstay of women. Conspicuous consumption, whether in the form of clothing, jewelry, or stylish pedicures, is their purview. They themselves can be trophies. They are like the jewelry they acquire, storing value to be dispensed with as needed. Their beauty is praised, which is a proxy for the value of their DNA. And in history, women were literally passed around as a way to negotiate power between kingdoms. And the etiquette teachers, the comportment teachers, the ones urging their children the most to have good friends, good education, etc., are the mothers.

You could abuse cognitive therapy if you mistake a distorted negative belief for a fixed inclination, like trying to dispute one's sexual orientation

What is the basis of one's stance toward something? Is it taste or belief? Some stances we take because of taste. You can't, for example, use cognitive therapy, to make yourself enjoy heavy metal or hip-hop music. That is unless your negativity toward those genres is based partly on a distorted negative belief toward those underlying subcultures. By extension, is it possible that some negative attitudes toward ourselves are not based on distorted beliefs, but a natural distaste or revulsion?

Most likely it's a spectrum, of taste and belief, and at the very least, cognitive therapy should be used to rule out the belief component. But beyond that, a different tool has to be used.
