It's just a statistical risk assessment in order to up chances of living the next day. It is a human survival skill to know what a risk is and avoid it regardless if ones feeling are hurt. It isnt the black kid in a hoodie that people fear, it's the 1000s of.videos out there of black "kids" in hoodies doing violent arrogant shit to innocent white people that has people sterotyping. If blacks behaved like most asians, there wouldnt be a fear of them. Very simple.
