Card-carrying Republicans, dupes of the Republican party, and Republican miscreants have been instructed to whine about political correctness when it suits the needs of the Republican party.
Sarah Palin wanted Rahm Emmanuel, Obama's first White House Chief-of-Staff, fired because he referred to Democrats as 'RETARDS.' When Rush Limbaugh echoed the same sentiments, she told people Rush is a hero for speaking the truth.
This duality of reality smacks of Nazism. Yes, Nazism. Adolf Hitler blamed the Jews for Germany's WWI defeat; hence, he implemented the Holocaust.
Reality was that Germany lost WWI because she got into a two-front war against large enemies, the same reason Germany went on to lose WWII.
