I don't like him either, but I've always been of the opinion that this new 'identity' trend is opening Pandora's box. First gender/sex, then race, what next?
People keep making up these identities for themselves to feel unique. There are men and there are women. There are straights and there are gays (and some people in-between). There's no need to convolute matters and invent entirely new genders and sexualities just because there's variation between archetypical norms. Variation is expected. It doesn't mean a person has to be something else.
Society shouldn't also be expected to play along with what are essentially delusions and made up words. Again, it's opening Pandora's box. Where do we draw the line? With the exception of genuine mental conditions, is there really any difference between a male that "identifies" as a female, a white person that "identifies" as a black person, and a human that "identifies" as an elephant?
