Someone obesssivly concerned with the enviroment, hypocritically, who wants others to suffer to enforce a static notion of nature.
That group that burned those Hummers are such ecomentalists.
An intellectually misguided, rationally challenged neo-hippie member of the pseudo-environmental division of the loony left, dedicated to the advancement of radical socio-economic policies such as cultural Marxism, political correctness, and other post-Communist forms of state-enforced social equality, using of course the supposed frail state of the planet to forward their agenda using scare-mongering tactics and/or dramatized and falsified information.
I once told a eco-mentalist from Greenpeace that trees absorb carbon dioxide from the atmosphere and convert it to oxygen, and she said, "No!" What a Muppet.
