I can kinda see what you are saying, but there is a certain tone people take when they are attacking you and that's the tone she uses every time she talks to me. And calls me cis like a little kid would call someone a mean name.

In a discussion about privilege I don't need to be reminded of what I am. It's not like I forgot. And when I talk to people about white privilege I don't call them white in the same tone as she called me cis. Though I have seen black people that do, and they tend to think all white people are evil and racist.
