As far as I am aware, Berlin is the only place that banned pro-Palestine protests. On Israel, while anti-zionism isn't illegal, you have to be aware of what is criticism of Israel and what can be interpreted as antisemitism or hate speech. Hate speech against Palestinians is also illegal, but it seems people rarely report such instances to the authorities. Remember, calling for the elimination of a people is illegal, regardless of their ethnicity or nationality. Anti-Germans tend to be just as guilty of it as their extreme counterparts.
