According to Vanity Fair, though, Felt wasn't Jewish, but of Irish ancestry and no religion. That's more likely, but there still may be at least one more mystery surrounding DT.
It would be funny if Nixon didn't make Felt head of the FBI because Haldeman thought he was Jewish, and he wasn't Jewish.
Felt was Catholic and Nixon thought he was Jewish because of his name no doubt, and Haldeman "confirmed" it, because well, he thought the name was Jewish too no doubt. Sad to think these guys were both sitting in the oval office.
It is not just the taboo. The sterotypes are less and less accurate, and less and less about matters that folks care about anymore, to the extent it still has any accuracy at all.
