I agree that Caitlyn Jenner is a very bad example of a transgender person. Not for changing her gender identity though. South Park spoofed the fear of saying anything negative about her well.

That said, I don't think transgender people are so because they've chosen to be so. Though I'm not close with any transgender people, I know it's not an easy position to be in to say the least.

If "giving people the option to be transgender" means not discriminating or being hateful or mean to someone who is, then I think society as a whole should give people the option to be transgender. Not doing so is akin to the absurd racism towards people for the shade of skin they have.

Let people be who they are. Don't hurt them. They won't hurt you.
