@BreakingBrown I think most of them are worried about their privileges under the current paradigm going away. If they had some type of useful skill (like medical, advanced engineering, etc) they would have no worries because they can easily leave. The others have no useful skills.
a lot of this was also because the CPUSA hated him and put shit in the Cubans' ears, he ended up getting his radio station cut and having to leave for China where his line was well received. The BPP didn't fuck with the Soviets and the CPUSA either and oriented towards the Chinese.
@BreakingBrown They got one they probably are thinking they can't control. It's always all hands on deck to sink anyone who will be a disturbance in The Force. I've seen this pattern play out a few times now.
