Go to any high school football game in a black neighborhood and you will see what I'm saying.
These "sportsmanship" penalties are nothing but cultural whitewashing. YOU think sports should be one way (no dancing, pointing, etc) and so you put that in the rules. I say that's a garbage. There's nothing wrong with a little celebration and having fun.
It doesn't harm anyone. The only reason it's banned is because it makes white america uncomfortable.
