Satire is not religion. Pastafarianism is satire not religion. Of course, if this bothers you, you could make it a religion by devoting your life and finances to earnestly spreading/practicing Pastafarianism.
This ruling has nothing to do with making a 'state' religion, it's just pointing out the obvious difference between satire and it's subject.
As a side note: If you don't understand what religion is for its practitioners, then you shouldn't be making fun if it as all you're really doing is making fun of somebody for something that you haven't taken the time to understand yourself.
