Honestly, a little reflection wouldn’t hurt. Not getting defensive and acting like a child would be nice. Not lashing out at the person trying to communicate something to you would be a good start.
How about not starting a YouTube channel on how bad white people have it? I know these guys make it look “cool” but trust me, it’s good for no one.
Instead, maybe try thinking about what just happened. Maybe listen to their reasoning for why they thought you said something lousy?
I know that “racist” word is scary. It doesn’t feel good.
