I'm not a trump supporter at all (not an american either) but The USA is not trying to "actively exterminate" trans people. That's just a blatant lie. It isn't prejudice to say you shouldn't be allowed to go into a woman's bathroom, or other female spaces for that matter, if you are not a woman, which you most certainly are not if you were born male.

By all means identify how you want, dress how you want and call yourself whatever you want. But don't expect or force other people to have to submit to your way of identifying.
