I think it is dangerous because it is playing into the hands of the right wing people

Shouldn't that be the other way around? Germany has an interesting history with the "right wingers" and genocide. Laughable statement from a laughable person.

If these people cared about Palestine enough, they wouldn't protest in a country which doesn't care. They'd go back over and help make their country less shit- Or join Hamas, or whichever org they align with the most.
