There is a Jewish Second Amendment organization. They need to recruit more. The Democrats are moving in the direction of Europe by allowing Jews to be oppressed by Muslims here. So the Jews really have no hope of being protected by the government. But they have every hope in the world if they want to protect themselves.
Fortunately that’s our choice most places. Interestingly of the 8 states with over 3% Jewish population, New York, New Jersey, California, Connecticut, Delaware, Maryland, Massachusetts, Florida, only Florida is shall issue, so you have to be politically connected.
