I am sure there are plenty of people (Evan for one!) who would argue that *any* religion offends human dignity though.  I'm not sure that visitors from another planet are any more malign than, say, some beardy bloke who periodically floods the planet and has his son killed!  And anything that encourages anyone to believe that they have their "lot in life" ordained by some superior being and that they should therefore accept this "vale of tears" and make the best of it they can without moaning about it is surely offending human dignity.

I do see a special sensitivity to this kind of thing given their 20th century history I guess, but I suspect they need to "get over it" sometime soon, and banning something like this is not going to help that process!
