I actually internalized this lesson years ago in a chatroom of all places. Back when chatrooms were still a thing I remember talking to some people online. Then a nigger gets in the chat and starts instantly making it niggerish. So I typed out, "Leave it to a nigger to ruin everything." Boy, the people in that chat turned on me quick and I had about 30 people wishing that I'd go die in a war. That was 18 years ago and I had anonymity online then.
