Tom Cruise Banned In Germany

So, Germany has decided to ban Tom Cruisfrom filming in their country. All because he is a Scientologist? I have to admit, he looks like a "nut case" when he proclaims the "greatness" of his religion. But is that religious discrimination? I just have to laugh at his beliefs! South Park did a show on the subject (which Scientologists sued over, and won, and cannot be shown again, ever), and I thought that it was too weird to be true. Here is what they believe, and South Park pretty much got it right:
They assert that 75 million years ago, an evil galactic warlord named Xenu controlled seventy-six planets in this corner of the galaxy, each of which was severely overpopulated. To solve this problem, Xenu rounded up 13.5 trillion beings and then flew them to Earth, where they were dumped into volcanoes around the globe and vaporized with bombs. This scattered their radioactive souls, or thetans, until they were caught in electronic traps set up around the atmosphere and "implanted" with a number of false ideas -- including the concepts of God, Christ and organized religion. Scientologists later learn that many of these entities attached themselves to human beings, where they remain to this day, creating not just the root of all of our emotional and physical problems but the root of all problems of the modern world.
O.K., so these guys are completely off the deep end, as far as their thinking goes. And because of Tom's crazed rantings about his beliefs, he has alienated himself from his fan base, why not just let him make another movie that bombs? Eventually, he will just fall off the Earth (and be re-born) and take up farming in Illinois or somewhere.
