You can paint lipstick on a pig, but it's still a pig.

Bruce Jenner can change his name but he can't change his gender. He's still a "he" no matter what he wishes to be referred to as. If a female wishes to be addressed as Mr. I can do that as a courtesy, but it doesn't make her a him. If they want to live a fantasy world, they can fool themselves but they can't fool nature or God. Squatting to use the toilet doesn't make a guy a "her."
First time a guy dressed as a girl walks into a restroom behind my wife, he may find a fist in his lipsticked mouth and teeth on the floor.
They can make all the laws to protect freaks that they wish, but it won't force intelligent people to accept warped behavior as normal.
