I think the reason behind all this is just plain misogyny. Some men resent women who love other women because the thought thatawoman could find satisfaction with another woman makes them feel impotent. So, men who may be predisposed to violence may be more likely to act out onabisexual partner for that reason. Lesbians experience sexual violence at high rates because they would be likely to turn down men’s sexual advances, and some men don’t react to rejection well (a guy spit in my hair once, but that’s hardly sexual violence of course). And some women get raped just because they are gay, which is of course straight up homophobia; although in my opinion, that word hardly covers it, because it’s not fear of gay people, it’s hatred.
