A long time ago when I was a child and I was ignorant, I observed that in the Hispanic hoods (I am Hispanic)and African American hoods there is a lot of graffitti compared to white neighborhoods in the cities there are less and in the suburbs there are almost nothing. Dislike and sterotype of nonwhite races was common in those days because they were considered uncivilized and slobs. But all men whether they are black, hispanic, asian, white are all human beings and what man is without flaw?
Street gangs are in the inner cities.They have symbols and codes.
