Probably 90% of “greenie motivation” is either
1) Feel good about yourself for caring for the erf.
2) Getting in the pants on someone who wants to feel good about herself for caring about the erf.
The remaining 10% are the communists using the “green” movement as a front.
Your general argument may be right. But I’m thinking it’s more like 70%/30%. I think there are that many communists in this country.
