"As such, they are not representative of child abuse in the US as a whole. For example, it is quite possible that middle class white fathers or mothers could be belting, slapping, or otherwise physically disciplining their children at a higher rate than other races. It simply would not appear in the statistics." - This makes no sense to me, this would be the group that precisely would go to CPS to report their parents because it isn't an accepting thing how it is in black households. An anecdote is look at most every black comedian, they always make a joke about being beaten by their mom or dad when they are a kid.
"This is incorrect. Black people do not beat their children more than any other group in the US. There are no statistics available on ‘beating’ by racial group available from which to draw such a conclusion. However there are statistics available on ‘child abuse’ which indicate it occurs more in Native Americans than any other group. You can find these statistics here: https://www.statista.com/statistics/254857/child-abuse-rate-in-the-us-by-race-ethnicity/" - you are simply wrong about this.

"The other thing about these statistics is that certain parts of the population are more likely to come to the attention of Child Services than others. As is the case with policing. Lower income families, families of ex-prisoners, families on welfare, families making use of other state services such as domestic violence or substance abuse help are all statistically far more likely to come to the attention of Child Services and therefore enter these statistics. Furthermore, each of these variables could be a contributing factor over and above race (although race may underpin these variables up to point - such as likelihood of being a prisoner - but even that can be explained by over policing and other factors besides race)." - I'd argue that a child would be more likely to report the closer they live to an urban area and black people are one, if not the most, urbanized races in terms of where they live. Whites are far more rural.
Unfortunately your argument doesn't stand. You talk about how it is "quite possible" that middle class whites or whites in generally could be physically abusing there kids more. Well the data isn't on your side and your argument is a "what if" and the gaps aren't small enough for me to believe that its just a margin of error due to unreported.
Finally, I brought the physical abuse of blacks up to postulate a reason why young black adults are more violent then other races. If you don't accept my arguments and the data then what would be a reason you would suggest why they are the more violent then any other racial group? Also I appreciate the civility of this discussion, we are discussing racial differences and that can get nasty so I'm grateful you arent assuming I have bad motives in bringing this up.
