The Left And "Identity"

So 'identity' actually means: who you are.
   But on the left it means some intersection of:
(a) Who you say you are
and
(b) How you show up in a worldview that basically sees only race, "gender," and sexual orientation (and maybe some other stuff like sex...though that is suspiciously real and biological, so...)
   So it's not just "What race / "gender" / etc. are you?" It's "What race / "gender" / etc. do you choose to call yourself?"
   Bah! Have I mentioned I'm against them???? I'M AGAINST THEM!!!!! OPPOSED! DO NOT LIKE!!!!11111
