They have seen a meteoric rise in recent years. Their sister/front organisations like ANSWER, Codepink, People’s Forum, BTnews have all become household names. When I look at protests in the U.S., it seems so many of them are organised directly, or indirectly, by them. In comparison, organisations like the CPUSA or the DSA are lacking behind.
How and why?
Court cases with information about when the spies joined the groups. I don’t remember the exact case right now, I suspect it was an environmental org that spun off a small marxist reading group, one of the big cases had spies sleeping with and even having children with members of orgs.
I remember listening to an interview with a guy who was spied on in one of those groups, I forget which podcast though… Maybe TrueAnon or QAA?
