Here is an article from columnist Susan Estrich regarding the recent situation in Germany: Tom Cruise And The German Problem.
I particularly agree with:
"... the film Mr. Cruise is set to star in has absolutely nothing to do with Scientology. Mr. Cruise is an actor seeking to work in his craft, and the Germans are seeking to prohibit him from doing so because of his religious views. If any country should be sensitive to the harms of religious discrimination, it is Germany."
