If you read other sources it seems not to be without reason and they did the same with a self acclaimed nazi prinz before. They investigate then raid when there is enough concern, and if they find evidence that the group goes against the german constitution, they shut the group down.

There are radical islamists in Germany and its good they are stopped before spreading.
I am against the genocide, but there are islamists who want to push their woman oppression and other extrem views using the genocide to spread their views, both extrems suck.
AfD is a more difficult case because its a political party, but they are already being investigated. And have been assigned the far right group label. Kind of like strike 2 before a raid.
Looking at the treatment of women in Iran, I think 'slaves' is a huge overstatement. But I do agree that the way authorities are treating women in some cases is appalling.
