Negative generalizations are, at best, tangentially related to racism. Racism is most fundamentally, "I think blue people are better than green people, because they're blue." Speaking negatively, or positively, of blue or green people would not be racist. Refusing to associate with any green person, because they're green, would be racist. Considering a specific blue Nobel prize winning nuclear scientist to be dumb, because blue people have a statistically lower IQ on average, would also be racist. Observing that mentioned IQ difference and considering that it would be expected to result in a lower than average distribution of aforementioned Nobel prize winning nuclear scientists, would not be racist.
