Wait! LOL. First, there is no such thing as 'atheistic' values. Atheism does not come with a set of values. Second, I'm not about 'atheist rights' I'm about human rights. I seriously don't care, on a personal level, what you believe as long as you are not imposing it on others. I don't condone a government that would enforce atheism any more than I would condone a government that would enforce religion. That said, unless there is some atheist push-back, the Chrisitan right in this country could eventually corrupt our government so much, discard the Constitution, and encroach on human rights. It won't be enough to believe in a god, but it will have to be the 'right' god.
I am for a secular government. I don't think we should give tax breaks to churches for money they use to perpetuate their faith, although I think tax breaks may be nice for true and secular charity. Why should government support the perpetuation of a religion anyway? Feed the hungry. Okay. Noble. Get a tax break. Preach to the poor---that's your business. Tax the money.
Simply not believing in gods or fairies does not automatically translate into wanting to suppress religion. Religion somehow thinks that if it is not given political power, it is being suppressed. That if the person who disagrees with them today will be the person who jails them tomorrow. That's ridiculous. Atheists can behave poorly, but they aren't breaking any ethics of atheism. Atheism doesn't have a set of ethics. They can behave very well, but they are not upholding the ethics of atheism. But a person CAN shoot a little girl in the face, stone a homosexual, blow up a clinic, shoot an abortion doctor, dumb down the kids, and absolutely be upholding their ethical code.
