Don’t have to prove anything. Look who they are voting for in the USA today. The whole world knows that this administration is doing their best to make sure Israel looses any confrontation with their enemies, yet the majority of the Jews in this country still supports and votes for OBAMA, OBAMA
Your claim was not the Jews are voting against their interests by voting for Obama, a perfectly defensible position.
It was that “many Jews voted for Hitler.”
That’s what you need to prove, or admit you made it up.
