As far as I know, I've only ever known one #trans person. When I met him, he was a beautiful blond boy. When she died 10 years later, she was a beautiful young woman.
But she's not the reason I care this much about trans issues. I care about them because I care about me.
Every one of us is a member of some minority group - black, trans, female, ginger, gay, short, whatever. Just because your group isn't society's enemy today doesn't mean it won't be tomorrow.
