There is truth in what you say except the progressive movement isn't as cohesive as communism. There is no official manifest, no one one roof organization.. well, actually I think the Democrat party is the US roof organization and the UN is the international.
what about the newly created communist religion called environmentalism? If you don't recycle its a sin. If you don't destroy the evil corporations, its a sin.
I think its a slow, well thought out tactic.
Don't forget, everything is in disguise.
We'll have to figure out what the "manifest" is.
These are not stupid people we're dealing with. Some of these are geniuses.
