Telling racists that their behavior is racist, and giving them evidence as to why it is racist is not prejudice nor is it “hurting” them. People who appropriate my culture (and any culture) are the ones who are hurting others.

Give me a real example of how I hurt them? I do not insult them, or tell people to insult them. I give them facts, articles, evidence, insight as to why cultural appropriation is an act of racism. That is not a cruel thing to do.
