There have been a few that tried to stamp it out, thoroughly unpleasant places by all accounts.
However, my point still stands. And if you're talking about Stalinist Russia, Maoist China, or even North Korea, they were and are all exceptionally religious states. Just not supernatural ones.
I think it's entirely irrational to only concern yourself with the negative aspects of religion, and ignore the positives.
I don't ignore the positives, but they're few and far between compared to the negatives. I should also point out, that just because good work is done in the name of a religion, it says nothing about the truth of it's preachments. And I still maintain (this was first proposed by Christopher Hitchens), that no moral action exists that's been carried out by a believer, that could not have been carried out by a non believer. However, I don't even need to ask you to think of an immoral action that could only have been committed by a person of religion, you've already thought of it.
(Sorry, getting too into the religion side, again

).
There's a world of difference between opposing the beliefs, and discriminating against those who hold them, you are doing the latter.
If I oppose the beliefs, and seek to remove them, surely there's not a world of difference between the belief and those that hold them?
Nor do they guarantee the right of the state to discriminate against religious beliefs, but that is what you are advocating.
The main thrust of human rights revolves around states, not individuals, and what the state can do. The state discriminating is far, far worse than individuals discriminating, and yet you wish to use state discrimination to try and address the problem of individual discrimination...
I don't think religion should play any part, whatsoever, in our society, nor our state. Especially our state and government, you're correct in saying. I do see where you're coming from, and what you're trying to say, so please don't think that my replies are coming from a wall of ignorance, in that respect.
I think if the state wants to have a society free of discrimination on grounds of race, sex, sexual orientation, religion, etc, and makes laws to that effect, how can it be right to make one group exempt? Is it mere surprise that the one group we would offer a free pass to is religion? (Genuine question).
