Was Albert Einstein a 'Nazi apologist'?

If Ken Livingstone is a 'disgusting Nazi apologist' (John Mann MP) then so were Albert Einstein, Sigmund Freud, Primo Levi, Hannah Arendt and not forgetting Marek Edelman - leader of the Warsaw Ghetto uprising. Time to dust off an article I wrote about this for Stop the War Coalition. Better speak up for myself as well. My first street politics was being beaten up by real Nazis from the British Movement and my father - a major influence on my life, was one of the first Allied medics to enter Bergen-Belsen concentration camp after its liberation.
