I can definitely see the correlation between these so-called intellectuals & Hitler's rise to power.
I don't condone the German people for voting him in office(I'm Jewish, BTW). Nevertheless, I can see how they got so sickened by liberalism that anyone who promoted patriotism & conservative values, albeit perverted, would look good in comparison.
People fear a reenactment of Nazism here. Ironically, I'm more concerned about its coming from the left-, not the right-wingers. They're the ones in back of the Islamists & other kooks.
Agreed that the greater danger of anti Semitism comes from the Left, primarily because leftist doctrine puts the state (the people) in charge of society. So leftist anti Semitism would almost by definition be state sanctioned, as it was in Nazi Germany and the USSR.
Of course, modern American conservatives are now also leaning toward the idea that the state is more or less the shaper and arranger of society, so the dangers of right wing anti Semitism may be increasing as well.
