The word transsexual starts fights.

I know this from experience. I use the word to describe myself — I'm a transsexual person, by which I mean that I have medically transitioned, due to physical dysphoria, specifically to change my primary and secondary sex characteristics. And I have been called transphobic, by other trans people, for saying so. Not for gatekeeping anyone else's identity. Not for claiming my experience is more valid than theirs. Just for using the word.

This happens because transsexual sits at the center of one of the most heated intracommunity arguments in transgender life right now.
