Gender stereotypes are the reason kids get called fag or dyke at school, irrespective of their sexual orientation. This is real, and these kids are suffering terribly because of it. The number of student suicides because of homophobic bullying is on the rise, and it is something we can fight against.

I'm not saying there are no differences (although there are virtually no professions that need be gender specific - men and women can be equally proficient at almost everything), but that we should foster an environment where we minimize those differences because the outcomes of not doing that quite literally destroys lives.

All the evidence you need can be found by checking out the "It Gets Better" campaign started by Dan Savage.
