A new definition of being transgender offered on Tumblr: https://hoarder-of-stories-27.tumblr.com/post/690875886978859008/dont-have-a-cool-pithy-way-to-say-it-yet-but-i

“having or experiencing gender in a way that exists outside of or in opposition to societal norms”

The old one, "having a gender different from the one assigned at birth" might not reflect correctly experiences of intersex trans people.

Oh, you already have mentally ill in your bio... ok, that would explain it.

But it still doesn't matter. Let crazy lefties define words, it won't change your life.
