Calls for the boycott of Israel and denouncing the country as an “apartheid state” can be considered anti-Semitic, Klein, who is not Jewish, said further. On the other hand, the far-right nationalist Alternative for Germany party — shunned by Jerusalem and Germany’s organized Jewish community — has problematic views of the Nazi era but cannot be considered anti-Semitic as a whole, he argued.
AfD, despite their racist, xenophobic, and use of Nazi imagery in their marches, campaigns etc, is not antisemitic but calling Israel an apartheid state is antisemitic.
So you can be a Nazi apologist and not be considered an antisemite, but god help you if you call Israel an apartheid state (which it is!), you're an anti semite.
