I imagine that if I were gay and it came to things like laws that I felt repressed my rights as a person simply because I was gay, I'd speak up against such laws for example. But just some fool spouting off about how evil or immoral or condemned-by-God gay people in general are, for example? No, I wouldn't "defend gays" from such statements.
But this isn't really an analogous situation, because "attacks on gays" tend to be religio-political arguments. A woman complaining about how often she's had to deal with harassment or outright physical intimidation or abuse from men on a day-to-day basis isn't some kind of abstract argument or political musing; it's reporting observations. "This happens to me, a lot. It bothers/scares me. All the people who've done it so far are men." I can't imagine how I'm supposed to take another person's observations, of what happened to them, personally. It makes no sense to me whatsoever.
