Spread like locusts? lol As usual you dead enders ride the carousel of ignorance.  You haven't a clue as to how many Jews there are in the USA because the last Census was taken in 2010 and the next won't be out till 2020. Jews aren't even considered a race as much as they are an ethno-religious group. The fastest growing groups in the USA were Asians and Hispanics and now we have a fast growing nest of Muslims infiltrating many States. Don't be scared, the Jews aren't going to do anything to hurt you.  Now the Muslims? That's a different story.
