CO2 has PROVEN harmful effects. We're dumping a TON of it into the atmosphere. That alone is enough to label it correctly as a pollutant unless it's PROVEN not be doing any harm. You're so big on theories being proven, PROVE that one.
I don't know if you've noticed or not, but the lunatics are running the asylum on the right now. I don't deny there are exceptions, but there are plenty of indications that if you pull one at random, the good money is on them being one of the nutters. Hell, the right as a whole are apparently in denial that it was their policies that were running this country into the ground in the first place. To be fair and show I'm not just hating on the right, they apparently have a lot of company from morons in the middle too. And if the left had 6 unfettered years of running things (or 12 just running congress) I'd be happy to rant and generalize about any stupid shit they do too.
Aren't you the same person that labeled everyone who identifies themselves with a group as not worth listening to? In a thread for an article about how people deny and shield themselves from opposing viewpoints? Like that somehow made you different and not one of the exact people the article was talking about? Yeah, keep on proving yourself special, Mr. Independent.
