people that are smart will understand that following a sect that supports cultural extirmination (aka Mao) and full dictatorship (aka Stalin) all sugar-coated and spewed out in a nice utopian manner (aka Marx/Lenin) - is a bad idea.
those who are ignorant/too confused/upper class confused youth/revuolutionaries too old to quit after all these years will stay and sell the paper, push their leaflets and will yell "power to the people" whenever they can.
It a simple concept, really.
