Yup...its the sibling of what the libs have been pulling here for nearly a century: "Creeping socialism," aka incrementalism. What I ;like to call social terrorism.
They are the same types that migrated to trendy Stalinest terror groups like the PFLP, Bader-Meinhof Gang and JRA during that tumultuous period in the 1970s.
Unfortunately, what these "progressives" do not and will never comprehend is that they will be the first victims once the forces of darkness assume power.
By yoking themselves to a theocratic, fascist, totalitarian movement, they're basically sealing their own death warrants. If they don't want to believe that, they can just ask their fellow travelers-in groups like the MEK-what happened to them once their "revolution" was realized.
