What is it? Why is it so bad? or such a big deal?

Some governments have special benefits for religions, like not paying taxes.  L.Ron Hubbard wrote Science Fiction, which didn't do so well, so he used the same ideas and started a religion.  

This would be no big deal, it happens all the time (c.f. John Smith), but in this religion, Scientology, you have to give ALL your money instead of the more typical 10%, AND Scientologists believe that psychiatry is a scam, so some people who need help, and medicine, don't get it and get hurt.
