Left unity has always existed in real communist/anti-imperialist revolutions. Not every revolutionary was a bleeding heart Marxist, nor every anti-imperialist revolution. One example is Suharto of Indonesia. In any case it is misleading to present Marxism as a dogmatic procedure for revolution in each country. Most revolutions were primarily nationalist and anti imperialist, it just so happens that Marxism is the most useful and popular theoretical framework for such a movement.

On the other hand, utopian and ideal thought is often counter revolutionary. Shutting that down isn’t LeFtIsT iNfIgHtInG, it is necessary for a sustained revolution.

All mortal men are sinners compared with the Christian god which is perfect. No concrete thing can be made ideal. For this reason idealist thought is toxic to any real movement, even one which is progressive. It cannot allow the “birthmarks” of capitalism which Marx wrote about in his critique of the Gotha program. Any progressive movement that allows for idealist thinking is doomed to fail and exposes itself to the bourgeois elements that are eager to return to power.
