Most people don't reject violent revolution for the practical reason that it's a unworkable strategy but because they find the idea of going and lynching the capitalists is morally wrong.
Marx idea of putting philosophy into action brought along the politics of revolution.Bush's relationship with the "reality-based community" leads to misleading voters and ignoring scientific findings. In both cases the ideas get judged by their practical political consequences.
No need to lynch anyone: after all, Marx didn't feel that capitalists were evil, he felt that they were just doing what the prevailing economic system forced them to do: to squeeze profit out of workers to avoid being outcompeted and driven to bankruptcy by the other capitalists. But (most of them) are not actively evil and don't need to be punished. So you could just let them live but take their stuff, and there does exist wide support for the notion of forcibly taking at least some of people's stuff (via taxation).
