> Chomsky never denies the possibility of a genetic component to IQ, even IQ/race. What he denies are the ideological assumptions people make about the social consequences that must follow if those findings are true

The identification of differences between groups seem to be commonly conflated with the act of unfairly discriminating against a group with prejudice based on differences (perceived or real), which is kind of absurd when you think of some of the more superficial and obvious yet real differences. You clarify this very succinctly, but it is still abstract, and I find many people tend not to understand until given a more concrete example... this I find challenging to do without being prejudged as some kind of racist or sexist, so unfortunately I just don't bother any more, the world has become overly sensitive to certain subjects.
