Ok I think I was going the wrong way with my Gender topic. I think I should write about how times have changed and society evolved, women and men do not perform their traditional roles as they use to and do not dress the same as they use to. And women go to school now, work, vote, have careers. Men now take ballet, join the choir, join the cheerleading squad etc.

How can I narrow this down to an argument and thesis?

I'd narrow it down to this thesis:

Women were the first crossdressers.

Please refer back to my post about women wearing pants.
