I'm not derailing anybody. I totally believe that she should feel free to express herself and describe her experience with racism. Her use of the word "Karen" is intentionally dehumanizing white women. As you said, white women's feelings don't matter here. However, don't pretend that the use of the word "Karen" is benign or innocent, it's not. It's as dismissive as the white knighting trope you used to dismiss me.
