So many - note that, many - of them extoll their atheism and they readily attack "Christianists" for their traditional values. Modern leftists excoriate traditionalists as blithering idiots or backwood hicks, or worse. Especially in the context of same-same marriage, where the debate is so intense, even violent, the more you listen to these people, the more clear it is that today's radicals want a wholesale revolution in society's moral regime, so they can "have it their way."
In any case, Dinesh D'Souza explains all of this perfectly in his interview at Salvo Magazine:
Atheists spend a lot of time thinking about the motives for belief. Why do religious people believe these ridiculous things? When you turn the tables on atheists and ask them why they don't believe, they will answer, "Because we don't have enough evidence. We don't believe because there's no proof." But if you think about it, this is an inadequate explanation, because if you truly believe that there is no proof for God, then you're not going to bother with the matter. You're just going to live your life as if God isn't there.Hat Tip: Hot Air.
I don't believe in unicorns, so I just go about my life as if there are no unicorns. You'll notice that I haven't written any books called The End of the Unicorn, Unicorns Are Not Great, or The Unicorn Delusion, and I don't spend my time obsessing about unicorns. What I'm getting at is that you have these people out there who don't believe that God exists, but who are actively attempting to eliminate religion from society, setting up atheist video shows, and having atheist conferences. There has to be more going on here than mere unbelief.
If you really look at the motivations of contemporary atheists, you'll find that they don't even really reject Christian theology. It's not as if the atheist objects to the resurrection or the parting of the sea; rather, it is Christian morality to which atheists object, particularly Christian moral prohibitions in the area of sex. The atheist looks at all of Christianity's "thou shalt nots"—homosexuality is bad; divorce is bad; adultery is bad; premarital sex is bad—and then looks at his own life and says, "If these things are really bad, then I'm a bad guy. But I'm not a bad guy; I'm a great guy. I must thus reinterpret or (preferably) abolish all of these accusatory teachings that are putting me in a bad light."
How does one do that? One way is liberal Christianity—you simply reinterpret Christian teachings as if they don't really mean what they say. The better way, of course, is to ask where morality comes from. Well, it comes from one of two places. It either comes from ourselves—these are the rules that we make up as we go along—or it comes from some transcendent source. To get rid of God, then, is to remove the shadow of moral judgment. This doesn't mean that you completely eliminate morality, but it does mean that you reduce morality to a tool that human societies construct for their own advantages. It means that morality can change, and that old rules can be set aside. You can see why this would be a very attractive proposition for the guy who wants to live his life unmolested by the injunctions and prohibitions of Christian morality.
