What am I doing it correctly?

Girl: That wasn’t nice of you! It hurts! Me: That wasn’t nice of you to act like a Karen. You weren’t wearing your mask in public. Girl: Shut up Mexican! Me: Shut up European. Your ancestors traveled here and killed the natives, aka MY ancestors. Me: Mass Destruction 100

True story, this happen to me at school. She told me to go back to my country and told me I’m Mexican, since she’s American I told her “well, your European ancestors came here to my country and killed my kind”. I felt deeply offended by what she said, because it was very racist.

Yep, thanks for the assistance!
