>Such lies are meant to blame the Jews themselves for the most terrible crimes in history
This doesn't even make sense.
Hitler was ONE GUY.
Even if he had 100% Jewish roots, that doesn't change any blame going from him to anyone else, especially not the ones in the forced labor / medical experiment camps.
btw. why wasn't this a problem 10 years ago when haaretz reported about it? They even used it against Hitler, which is fair game.
