Yes, of course you are absolutely right. However, I am not sure that the Green Movement is really about being green either. Their lust for power is just as great as any Marxist or Muslim.
I stand corrected, see post number 7!
The Green Movement has been co-opted, and is heavily allied with the Marxists. That said, there are a lot of airy-fairy well intentioned useful green idiots. The Muslims and the self-declared Marxists are a lot more serious than your average tree-hugger. That's not to say that there aren't fanatic eco-terrorists, of course. Put differently, there are a lot of greenish idiots along for the ride, but there aren't too many "Muslim-ish" Islamists.
