I think that The differences in IS among different races is not necessarily racist. I do think that there are many flaws in how a standard IQ test measures intelligence. It is just not a comprehensive picture of cognition. Furthermore the use of IQ as a means test as to which races should be allowed to immigrate is a form of eugenics.
Btw I am not saying that the concept of measuring IQ is a joke. What I am saying is that the standard IQ test probably falls short of measuring all factors involved in human intelligence. This is due to the variety of reasons I have discussed previously.
