Plus there’s always scientology.
Germany does not recognize Scientology as a religion and sees it as a threat.
To the point that the late Chick Corea, a practicing scientologist, was not allowed to play gigs at any publicly-owned venues, only private ones.
And when I worked as a teacher/tutor in Germany I also had to sign a document declaring that I was not a member of the Church of Scientology.
