Neither does playing Final Fantasy provide an evolutionary useful type of power, Baal Houtham. People are still compelled to do so, because not everything is determined by evolutionary advantage.
You’re assuming the conclusion that you think fits – men rape men in prison because they want sex, but women outside of prison because they want sex with women more – but you aren’t providing any reason why that must be so. If raping a woman is more desirable because it’s being driven exclusively by sex, then homosexual prison rape is explained in that way, sure. But if raping a woman is more desirable because it’s being driven by power, or by convenience, or by politics, or literally anything else, then homosexual prison rape can be explained in those ways, too.
What I’m saying is that the fact that rape fulfills a sexual urge isn’t the end of the inquiry. There’s clearly sexual gratification taking place, so it’s axiomatic that rape is “about sex” in that sense - there’s sexual intercourse taking place. But assuming that because the act itself is sexual we’re obligated to explain it in the context of normal sexual relations is a massive trap, I think, and it leads to the kinds of terribly flawed arguments that are going on in these threads at the moment.
Keeping it in the prison context might actually make some sense here: imagine a 17 year old goes into a correctional facility. He hears a lot of threats and a lot of old-timers talking about what they’re going to do to his ass. Sooner or later, he finds himself in a cell with some other dude who demands some kind of gratification or he’s going to cut his throat. He doesn’t want to, so he fights back. The guards take some privileges away for making trouble, and put him in a cell with a bigger dude next time. Let’s say he fights back for a couple years, he gets cut a few times, cuts somebody else a few more times, breaks a few bones, tries to kill himself and gets in trouble for that, maybe, and eventually he gets worn down enough that he says, you know what, whatever, I’m just going to let them turn me out. They broke me. They win. I’d rather be a punk than have to fight every day of my life. So he does. And every day or so for the rest of his time there, one of a few older inmates rapes him, and they call him boy or bitch or faggot. And he calls them daddy or big man or something like that.
Now, tell that guy that what happened to him was just about the other inmates wanting sex, and that, well, he was a young attractive guy, so it makes perfect sense that he was desirable. Nobody had anything against you, really, they were just horny. Really it’s a bit of a compliment. And then explain to him the ways in which he could take responsibility for the situation, since his attractiveness is a deciding factor in whether or not he gets raped. Not that it’s his fault, of course, but really, he could have taken some steps to not make himself such an obvious target for those other guys. It was wrong of them, yes, yes, of course, but hey, the penis wants what it wants and there’s no need to make this into some kind of political thing. It’s not like they had some anti-you agenda; they just weren’t being very considerate.
