You are correct. The Greens want to destroy the economy ... because it creates pollution.
Why do politicians listen to Greens, Gays, La Raza and other radical groups? Because they threaten to disrupt.
Eventually conservatives are going to have to get activated and began playing hardball with the politicians.
Look at John McCain. Other than on Iraq, he listen to the Leftish Radicals as well.
I question this. Physical disruption(s) can be countered with force. The disruption they threaten is financial. Though the numbers in these groups -- the Greens, Gays, Poverty-Pimps, etc.-- are minute, they are focused like a lazar, while the rest of us are a scatter gun.
