I think it's stupid to talk of going "back home" after more than 60 years. This is a new generation, Israel is their home. But the thought of Jews living in Germany is by no means offensive. Right now, almost 100,000 of them are living here, and those that I know personally are nice people and seem to be doing fine. Germany is by no means perfect (I would like to get out of here myself), but I don't think it's offensive to suggest Jews live here.
