Sure it is, after all they give the taxexempt status. A pedophile could declare his sexual deprivation as religion...
After all the hackers could declare that theirs is a religion with the ultimate goal of getting salvation by destroying Scientology....
The 2 examples you gave are completely irrelevant to Scientology being a religion and no one in their right mind would accept those as religion. But Scientology identifies itself as that. Im not going into the tax exempt status and whatnot, Im merely arguing from a moral point of view.
