That might be true, but that's not what that textbook says.
I just said that's why I disagree with the textbook. The passage was well-intentioned, but poorly written.
I don't think it's about social positions, it's more a result of gender stereotypes that men are perverts and molesters. That's what causes some men to be wary of gay men, and some women to be wary of heterosexual men.
You don't think there's a connection between gender stereotypes and social positions? Don't you think that gender stereotypes are one of the
reasons social positions are what they are? Men are leaders; women are followers. Men are dominant; women are submissive. Men are active, women are passive.
Consider for example the issue of homosexuality in general. Most Christians are opposed to it because the Bible condemns it. (and it does, quite explicitly; I'm not going to violate forum rules by even attempting to argue against what it says).
However, you'll notice that the Bible only ever condemns
male homosexuality; IIRC, the issue of lesbanism is mentioned only once, in passing, (I forget exactly where), and not necessarily condemned. Why? Because they frankly didn't care what women did. In the patriarchal society of the Jews and early Christians (I know the word "patriarchy" gets used and abused by feminists, but in this historical context, that's exactly what it is), the very thought of a
man assuming a woman's role (epecially regarding sex) was utterly degrading and the ultimate humiliation. What women did -- so long as they remained faithful and didn't call the legitimacy of heirs into question (let us remember, that marriage was originally instituted for exactly that purpose) -- didn't even register.
I would suggest that it's the same case in the showers and locker rooms -- if the gender stereotypes get flipped, so then do the social positions.
