Ok, Marx, but did Freud do wrong to you? In his book on psychology of humor, half of the jokes he brings are Jewish ones. In many cases, I did not realize they are THAT old.
Beitza tells us that Hashem gave us Torah to train us in derech eretz and limiting ourselves. Otherwise, we are have so much hutzpa (azut) that we would not leave space for other nations to live in.
Obvious corollary is that Jews without Torah would mess up the world … It does not matter whether it is their own fault or their grandparents, as long as they have national azut and lack Torah restraints, this is bound to happen.
Second corollary is that those who learn torah but somehow do not acquire derech eretz are not much better.
