Well, do stupid displays of religiosity turn you off religion? Do idiots waving the flag turn you off patriotism? Do stupid people advocating sex make you turn abstinent?

I mean, really, some of these responses are silly. So there are idiots who advocate environmentalism. Oooh, well then, let's not have any of that, no thanks, I hear there are kooks who like that.

Happy to agree that there are causes and advocates of conservation who are off-base, distasteful, and generally wrong. Doesn't change the fact that renewable energy is going to be big in the coming century, nor that perfecting closed-loop living will be key to colonizing something besides this rock called Terra, nor that some form of balancing our power with the ecosystem's will be necessary if we don't want the planet to shrug us off like a bad flu.

(Personal pet peeve -- people who say that "the planet is dying." No, idiots, the planet will be just fine, just dandy. We don't yet have enough power to destroy the planet, or even come close. What we could potentially do is make life very uncomfortable four ourselves, which is bad enough, so no need to go hyperventilating about the planet. It's survived 98% extinctions in the past, and bounced right back. Sure, it might take a few million years, but that's nothing to a planet.)
