Not trying to be sexist, but why does it matter shes a woman on this forum in the first place? It sucks, but there are places on the internet where just stating you're a woman gets you extra attention or help from desperate men. So maybe the forum is just tired of people coming on, stating their a woman whether true or not, and getting help way quicker than if no gender was to be said at all?
I know it paints me in a bad light but whatever, there is no reason to go on the internet and state your gender unless you're looking for extra attention. Your friend could have just asked the question and left out gender talk completely. There was no need to state she was a woman.
I know this a pretty sexist example, but viva la dirt league put out a gaming video explaining why some guys are over it.

I'm not trying to say guys acting that way was the right course of action, I was just giving my two cents of why it may be happening.
