I'm a secularist in the First Amendment sense:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof...No law. Full stop. No conditions, no exceptions.
Furthermore, I'll go the First Amendment one better: I do not support any coercion regarding religion beyond rational, critical analysis and my personal disapproval. I won't boycott an organization because of the religious beliefs of its management or ownership. I won't refuse to trade, I won't march, demonstrate or picket on purely religious grounds.
Of course, I distinguish religion from politics. I consider "religion" to be unfalsifiable beliefs about the nature of God. I consider politics to be any attempt to control, regulate, promote or discourage actual behavior. I'm not against controlling behavior per se (I definitely think that we should control and discourage the behavior of those who would rob, steal, rape and murder), but as a citizen in a democracy, I'm going to fully participate in our moral and legal discourse, and use whatever means permitted by law and custom, coercive or not, to advance my views.
But I am anti-religious. I do in fact consider religion to be not only false, but malignantly false. I don't consider all (or even most) religious people to be evil, but I do consider all of them to be mistaken in a way that does in fact promote evil to some degree. Since my argument is indirect and subtle, and since I myself might well be mistaken, I call only those people evil who are directly malicious.
I'm direct and blunt in my speech. I call God-belief the equivalent of belief in an invisible sky fairy. I'm not stupid, though, nor am I poorly-read: I understand that many people have a construction of God considerably more subtle than that. On the other hand, I think that such subtle constructions are vacuous, and therefore philosophical bullshit.
