Sorry I don't understand what you mean. What about the anti Muslims?
And yes, we should punish those who commit crimes rather than the ones who aren't.
Everybody is talking about German guilt standing in the way of recognizing faults with Israel and I don't think that's what's happening here. It's rather that now all the actual anti semites are coming out of their holes and mix with people rightfully opposed to Israel's actions, amplifying the hate against Jews in general.
If only more people would understand this, we would already have world peace.
