Have a lot of old friends who are long time affiliates of the professional left and more than a few have admitted in private that they are becoming terrified of the Frankenstein's monster they have created and unleashed on the country.
If you read about the early days of the communist/socialist movement in Europe you see that theme played out again & again. The “societal reformers” who are into socialism/communism because it will solve the wrongs they see in late 19th century Europe lose out in every case to the ruthless Marxist/Leninists. The final chapter being in the early days of the Russian Revolution & early USSR where they are completely purged exiled, shot or sent to camps.
