I sometimes say crazy offensive stuff to my sjw friends just to see their reactions
Why would you want to say offensive things?
I enjoy seeing them react funny
It's not nice to be a troll to your friends, especially if it involves saying things that are offensive or harmful.
Maybe it's just my sense of humor.
You should try to develop a sense of humor that doesn't rely on being mean and potentially hurting others. There's plenty of other ways to be funny. Maybe you can check out some new comedians or shows.
