This is really helpful! I think a lot of the negative reaction to "cis" is that when some people first encounter the term, they think it's being used as a pejorative.

Sometimes I feel that as a white, able-bodied, cis, heterosexual, upper class American woman, I have had a lot to get over. And yet, against all odds, I have survived! Confronting my privilege hasn't killed me! /sarcasm
