Politicians are politicians. The "why" or "how" are questions to ask them. Einstein never claimed to be a genius. Same for Stephen Hawking. A real genius doesn't know any other way to think. Trump thinks he a genius and has said so. He brags about how smart he thinks he is.
Anyway I agree with a man of true genius.
In the “God Letter” Einstein covered the Hebrew Bible/Old Testament claim that the Hebrews/Jews are chosen by God “above all people that are upon the face of the earth.” (Deuteronomy 7:6) when he wrote, “For me the Jewish religion like all other religions is an incarnation of the most childish superstition. And the Jewish people to whom I gladly belong ... have no different quality for me than all other people. As far as my experience goes, they are also no better than other human groups, although they are protected from the worst cancers by a lack of power. Otherwise I cannot see anything “chosen” about them.” (Sadly, now that Israel is a nuclear power, we see it is the bully of the Middle East. Israel has the power and uses/abuses that power to take what does not belong to it in regards to Palestinian lands. It exhibits “the worst cancers” by its abuse of Palestinian people and acts of state terror such as the murder of the American activist Rachel Corrie and the persecution of the man who warned the world about Israel's growing nuclear arsenal, Mordechai Vanunu.)
I'm sure it's not the answer you want. Deal with it.
