Are you a feminist? (If so why, if not why not?)

Might help also to describe what you think feminism is, since it's one of those terms that is overloaded.

I once had a physical therapist tell me she wasn't a feminist because she thought women couldn't be as physically capable as men when serving as soldiers, and seemed to believe feminism requires treating women exactly like men.

I told her I was a feminist because I believe in equal rights for men and women, an idea she did not seem so opposed to.
