There are active communists in DSA. Many of them are also in communist orgs. DSA, as a big tent Leftist party, draws in everyone from social liberals & socdems to anarchists & marxists with many of these people also belonging to other Leftist groups/factions/parties like PSL, FRSO, CPUSA, etc.
Don't think for a minute that when they start snatching up DSA members that they won't go after their affiliates, friends, family, etc. outside DSA. This is literally what they did in Chile, in Indonesia, and everywhere else a White Terror was implemented.
This is the FedGov openly preparing to liquidate the entire U.S. Left and using DSA as a springboard to do it. Be concerned.
