I doubt the offense was intentional, but to suggest that the Jews leave if it gets too tough probably would rub a lot of people the wrong way, given their history in Europe.

To be fair to you, I kind of took a cheap shot. Looked at it from a rigidly logical and unemotional standpoint, you actually make a valid point. When a place, a neighborhood, or a nation becomes too hostile for anyone (not just Jews) to live in safely, it may be time to seek other environments. There are places in America where this applies as well, particularly in some cities.

A lot of Jews left Europe of their own accord before WWII, while the threat was still largely implied. I'm sure they were glad they did later.
