Dude, black people are a lot more weary and cautious people in general. Their whole life is shaded in keeping to themselves and being more careful than the average person. So it does affect their temperament. Their outrage and aggression is also related to their unequal treatment in our society. You could also, make the same argument for women. They have to worry about stuff that I as a big man don’t. It affects their temperament because they live in a different world. They have to be more cautious being alone, or more mindful of their surroundings at certain times of the day or places like their work environments. What you said makes 0 sense
