Religious groups seeking and exercising political influence are potentially far more dangerous to society than any amount of (non-violent) pornography. Religion promotes ignorance, sexism, violence (in the guise of discipline / self defence / national security) and complete and unquestioning submission to religious authority and religious dogma. Evangelical / fundamentalist Christianity is no better than Islamic extremism. Look no further than the US or the Middle East to see the results of letting religion infiltrate government.
We must resist interferance by minority religious groups on every front, or they will slowly chip away at our democracy, our institutions and our culture until they have forced us all to conform to their prehistoric ideals. Yes, religion really does suck, and not in a good way.
(Yeah, I know this might sound a bit paranoid, but frankly I think we have reason to be.)
