The problem with having old white cats.
The problem isn't that you've offended people, it's that you refuse to stop. People have asked you to stop, and instead of stopping you say "It's just a joke, chill." Because you're famous now, you can't talk like you do at home or in public cause no one here knows you. So, even if you don't mean it, apologize and watch your words. People take things from famous people way too seriously for no reason, but it's a problem they need to deal with.
