Jew bashing was a easy fall back position in Europe. Hitler seized on it because it didn't take to much work to "prove", however untrue it was. He used the stab in the back argument, he used symbolism, and he used his aryan greatness argument..all borrowed ideas, to climb to and maintain power. Hitler was sent to investigate the Nazi party before he ever became one. I don't think 240 is wrong..he's just not getting very specific. Living space was another Hitler idea all used to gain and maintain power.
