I hope you see that piece is sarcasm, guys who call themselves feminists to get pussy are not really feminists, that's the point.
But anyways, it depends what you mean by feminism, there are feminists I agree a lot with almost completely but there's a portion of the new feminist millennial version that I can't digest. So I have no idea if I'm a feminist or not nor do I care so much about labeling myself.
I have dated self-identified feminists and I have found they're not the crazy man-hating stereotype many in the right make out to be. I have found they're actually very intelligent and understanding of men too or at least they are really interested to listen to what men have to say as long as they don't do it in insulting or disrespectful ways. Of course there are other feminists that are exactly like the stereotype but I wouldn't date one of them. The concept of feminism is now used so widely and to cover so many subjects that I think it is losing its usefulness as a category, that's why relatively few women and even less men identify themselves as feminists, they don't want to be thrown into a bag with all that confusing mess.
