If he said this in a different context about Europeans or the Japanese national team the reaction would be different. When it's a black man dissing fellow black men the excuses pile up.
Same ones saying "he's just joking and trolling" don't understand when you joke in public you give others from different races/ethnicities the opportunity to move the bar of disrespect via "joking". He was so ignorant he had no idea Embid is from Cameroon a country completely different than South Sudan.
It’s funny because his cousins(Embiid)are more likely to be from America or Cuba than South Sudan
