"It's been proven beyond the shadow of a doubt that we are the cause."

Says who? There is evidence that supports the idea, but it's not proof. I'm a supporter of the theory myself but I'm not so closed minded as to accept the biased rantings of agenda driven environuts as fact. I also don't feel it's worth insulting people on the internet about.

If you feel I'm not worthy of your time, fine, go argue with someone else.
