It's easy to forget that Bertrand Russell was one of the first to see and write about the essential tyranny and falsehood of the Soviet system (1920), or that Einstein chose to come to this country in 1933, the moment Hitler attained power.
It's wrong to assume their criticisms of American society implied a love for Soviet Communism.
Bertrand Russel was a staunch SOCIALIST/MARXIST to his dying day.Like so many of that ilk, he thought that HE could make that system work, if only given the chance. Wanna try again ... talking about things you don't know much about ? LOL
Not only was Einstein a Jew, but the Nazis were going afyer Commies, as well as Jews and others. Anyone, with sense and opportunity, was leaving Germany, when Einstein did.
