Anti-racism is also racism, but with a different target. As I understand it, Islamic Jew-haters are quite welcome in Germany today. More than Jews. Hitler and the Nazis were allies with Muslim Jew-haters as well. I don’t see the political climate as being too much different than under the Nazis.
You understand wrong.
Here's some other stuff you should understand:
1. Germany plans to deport migrants guilty of anti-Semitism, while migrants who target white gentiles and Christians are no problem.
2. German police provide extra security for Jewish centers and synagogues, while white gentiles and Christians are left at the mercy of Muslims and Africans.
3. Jewish organizations in Germany support Muslims. I still remember hearing on KABC-AM in the mid 1990s that Germany restricted Turkish Muslim immigration. The Simon Wiesenthal Center denounced Germany for returning to its racist Nazi past. Stinging from Jewish criticism, Germany quickly rescinded the restriction.
