Very true. The FBI tried to cause and exacerbate as many fissures on the left as they could.
Having said that, all thru american-history, the various leftist groups, have done a SUPERB job of wrecking any chance of big-left-solidarity. Get ten leftists in a room, and in two months eleven separate groups will form. And the eleven groups will spend more time hating on other leftist groups than in fighting the system.
