So we, the government of the US and our white members of society have conspired to create an environment of constant stress for people of color. It's something I can't conceive of. So I understand though how reactions to the same occurrence, say being pulled over by a police officer, can be so different for white and for blacks. A white person expects a warning or ticket and then goes on the way. A black person expects something different - worse and stress levels rise and reactions can be a reflection of that stress. Chronic stress is also a killer in that many chronic diseases are aggravated and complicated by stress. No-one should live with such life shortening stress in the richest nation in the world!
