If someone says that they are really Napoleon, they are sent to an insane asylum.
But if a man says that he is a woman and you refuse to provide him services normally reserved for women, YOU are taken to court and forced to pay a large fine.
This is the result of Postmodernism, a world-view that says reality is whatever we decide it is. Future generations will laugh at this 21st century insanity. But it's no fun to live through.
