Is it just me? or do others agree that hardly any black peoples are disrespectful to their parents?

it seems most, if not all, black children are respectful, afraid(in positive way) of their parents. even those that are very selfish and disrespectul to everyone eles seem to be scared and respectful to parents. i don't remember seeing any black people misbehaving to parents. some of them may do bad things, but they never talk back to parents, or give attitude while i see all kinds of misbehavior in some other races. i work in clinic and i see all kinds of peoples and notice black parents seem to have most power over their children. i'm non black. how do they do that?
