You conveniently ignore the religious aspects of modern left-wing thought in the environmental area. Who are Ghandi and Nelson Mandela but modern-day saints who can do no wrong? Nobody is allowed to ask how Mandela's people invented necklacing because it is heresy.
Be real, real careful about claiming that science supports you and you alone. It has a nasty habit of turning against you. Because it is, you know, evidence-based.
Dictatorship is an innate characteristic of communism. I'm not sure how you learned otherwise. It's not like they keep it a secret. Communists are quite proud of the fact.
"You are dictatorial." My dear sirs, you are right, that is just what we are.

-- Mao Zedong
