On the one hand, it's sad but true. It would be great to see more female gamers so this sort of thing wouldn't even be an issue, but the truth is gaming is heavily weighted towards males.
On the other hand, complaining like this only hurts your cause. If you're upset about not getting respect, crying about your lack thereof only makes it worse.
As I've seen, people seem to be making the obvious suggestion of just gaming without the headset. I agree entirely. I don't even own one, and wherever applicable, I mute all other players. Not because their reactions to me specifically, but because I loathe them before they even speak.
In all, it's tough to decide how something like this could be resolved, other than:
Ignore the idiots and just keep gaming.
