Asimov appeared to feel uncomfortable with those who thought they were better than others because of their Mensa status, and some he states were typically right-wing. I am entirely unclear though how the claimed racist ideology of John Campbell Jr is related. > I miss Isaac Asimov, and I miss the America that created him. An America with a typically right-wing Mensa bias (and likely upper class society)? That's the America that the author misses?
