My wife's creepy racist incel uncle had a fit once when we went into a store and he saw himself on the security camera. He said he doesn't like seeing himself. My sister had the same reaction to seeing herself pre transition and apparently it's a common theme among trans people who haven't realized it yet.
I know it's a bit of a tangent, but he's rabidly transphobic up to the point just short of being blatantly hateful. He's obsessed with my sister and other trans people and made a lot of obsessive and creepy jokes about dating them.
This post triggered my PTSD.
