There is a reverse to PC, which is the glee in breaking the PC orthodoxy. It can go to far, like the attempts of some to try to contextualise Hitler.
The problem with Gottfried's peice is that he plays fast and loose with facts for his political agenda. Worse his article fosters hate as a political tool. It is the mirror opposite of the PC attack.
Gottfried opposes political correctness, whether it is proposed by liberals, Marxists, or neoconservatives. Gottfried occupies the same status as an independent Jewish thinker, that Thomas Sowell occupies in black America. I consider both men to be among the bravest and most brilliant social critics in America.
There is a difference between beeing brave and supporting any cause.
Some people get hysterical and see any attempt to speak of the pain the Germans suffered under Wiemar or during the war as anti-Semetism, because Neo-Nazis use the arguement.
Gottfried sees the factual attack on Isabella I as worthy of attack because the PC left might use it.
Both are knee-jerk reactions and unbecoming of otherwise lucid thinkers.
Sowell has never defended those who enslaved blacks. Gottfried is doing the equivalent.
