The reason that black man … are imprisoned in numbers enormously disproportionate to white men is because black men commit an enormously disproportionate amount of crime compared to white men.
That is illogical unless you fail to distinguish between actual acts of crime and police statistics. It is like looking at stats and saying most drug-takers are from lower class backgrounds when it seems pretty obvious that those from wealthier backgrounds are far less likely to get busted. And as regards this blindness to the weakness of stats you claim:
… whites commit far more crime than Asians but fat less than blacks.
Does sound kinda racist the way you frame it… even if it is based on stats. The correlation could be explained by many other means.
