"So what if we face extinction because of our fantasist beliefs? At least we'll go extinct being what we are - Cowardly, self-indulgent sybarites with a fatuous faith in our own superiority. Merry Christmas all."
Interesting comment. Particularly the somewhat ironic Merry Christmas.
I don't think it's going to be an issue of outright extinction but more of a long term polarization. There are some very dedicated Christians who at more of an emotional and religious level have already gotten the message loud and clear. They're already having children like mad and home educating them to boot. And they're teaching their children the importance of doing the same thing. Just because you don't read about it in the lamestream media doesn't mean that these folks aren't out there.
The rest of our society who isn't interested in reproducing will not be relevant in another 50 years. They've already self-selected themselves out of the gene pool.
