What he says about the (sometimes correct, sometimes incorrect) assumption that white guys aren’t as gifted in basketball is probably true. But, seriously, who cares?
For many years it was considered the height of racism to observe (correctly) that blacks were more athletically gifted than whites. Everybody had to ignore what was obvious and agree with the libs that all races/ethnicities were all the same athletically.
Now it has become so obvious to even dimwitted white libs that blacks are superior to all other races in terms or running fast and jumping that it can't be denied any longer. But now and again slow, white libs like Chait have to resurrect the "we're all exactly equal" myth. You can't let libs get away with their lies. Every time they lie, they have to be challenged.
