This is a good question! Honestly I can't even think of a time. Usually when someone says something insulting or hurtful, I just lose respect or consideration for them. After all, it says more about them than it does about me.
To add an example, I recently got told to "go back to my country you [lazy racial slurs]" by a MAGA loving shithead neighbor.
I was born here, and the old asshole who said it emigrated here less than a decade ago. It was a flabbergasting experience.
