Jews DID have a bad rap in the 1930s. In addition to having a lot of identifiable Organized Crime figures in our numbers (Wikipedia lists over a hundred) there was a disproportionate number of anarchists and communists in our Tribe. And people seriously argued that letting refugees from Europe into the US would allow the Nazis to sneak people in who claimed to be refugees.
Meanwhile, most of the 11/13 terrorists in France were EU citizens from Visa Waiver Program countries who could have traveled to the US at any time with no vetting. All the hullabaloo about Syrian refugees is just fanning the flames of bigotry while doing nothing whatsoever to keep dangerous people out of the country.
