I understand your mindset, but you have misconstrued where layman (and I) are coming from. I’ll try to explain layman's 'racist' avatar.
He is using a stereotype of black people but it is a positive, not negative.
It’s the stereotype of the black male who cannot tolerate the enormous amount of bullshit in this society, and isn’t afraid to call it out. It is meant respectfully to blacks, not a dig. Does he take it to/past the extreme? We all do at times.
You will probably Dismiss that as goofy too. Society is divided by a hell of a lot more than racism.
