The old time conservationist orgs like the Sierra Club document the migration of the old Communists into the conservation orgs when their Garden of Socialist Eden in the USSR collapsed and Communism for a little while fell into world disrepute. As “greenies” they don’t carry the stigma of Stalin and Mao and GULAGs and slaughter of “deviants” but they are the same people and will use the same methods when they attain the power to do so.
Yes, wolves in sheep’s clothing. Many still don’t see that though.
