That isn't all that happens, as you can see from the comments like "Oh, yes, men have it so hard" whenever a situation that favors females over males is brought up.
It's part of a culture, one men perpetrate just as much as women if not more, that says "women are the only victims of sexism." If that statement doesn't seem immediately idiotic to you, the best I can offer right now is this:
Reverse discrimination sucks for whites, maybe I should question every submission that is authored by someone who isn't white?
You'll note that I address male taboos about sex in other posts, but ironically it's probably not what you want or what you're really getting at without being explicit about.
Do you understand that "any female-positive topic" -> "what about the menz" is exactly the problem with this attitude?
It would be nice if "gender equality topics" weren't exclusively "female-positive topics", and that the topics about how men get the bad end of sexism weren't immediately met with sarcasm and derision.
