most of them by the time the actual violent clashes happened certainly werent maoists. Yeah there was a significant % of the protestors that were coming from the left of the CPC but you have to remember that the unrest span month(s) and many cities. In Tainanmen by that point in the movement and leading to that the make up of those that stayed and engaged in lynchings and clashes with the PLA and police was solidly "pro-democracy/free-s[peech/liberalism" youth. Also western intelligence focus and assets had already zeroed in in Beijing and those elements after smelling blood from the more organic initial country wide unrest.

I always enjoy re-watching the full "Tank Man" video, with the "brutal Chinese tanks" awkwardly trying to bypass the protestor and patiently waiting him out. I think libs just see that single frame and fill the gaps with their own experiences in their countries in thinking that the guy got ran over or something. If you try that with a secret service car they might do just that.

The key reason this kind of lazy propaganda works is because people want to believe it. It leverages the latent racism and capitalist realism people have internalized living in decaying western societies. The idea that a country that doesn't follow liberal ideology could be more successful is a complete anathema to these people.
