P.S. I am not being hateful
You really don't think you're being hateful?
Yes, I'm really not being hateful
You shouldn't say you aren't hateful if your messages contradict that. You should be kind to others and not say anything if you don't have anything nice to say.
Stop it
I know it can be hard to admit our behavior needs changing, but you'll never be a nicer person if you can't accept when you say things you shouldn't.
