I don't. My attitude is more of a political/philosphical one than a policy one.

My take on the First Amendment differs a bit from the government's. I interpret "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof" as incompatible with making an IRS category about them. This is because it requires the government to decide what does and does not count as a religion -- which seems to be, at least in spirit, what the first amendment says should not be done.

That said, this is not really something that I get terribly upset about. In practice, I don't think a great deal of injustice results (meaning that if I'm going to make a big stink about injustice, there are much bigger fish to fry.)
