I'd recommend just asking there. Trust me, we're not mean unless you're acting in bad faith (and it seems like you are not).

Lemmygrad.ml is not "extreme" in any way. We are Marxist-Leninists. At its most basic level, we believe that the Soviet Union and modern China were and are on the right side of history; not perfect, but fundamentally good. You may not agree with them, but neither of these are radical ideas.

what would lemmygrad.ml’s position on the tiananmen square massacre be?

That the death count was low (a few hundred), roughly half of which were on the government side (military and police). It was not a massacre of defenseless students, but a clash between armed radicals and the police. And none of the conflict actually took place in the square; the government dispersed the protest there without bloodshed. It took place in the city at large (which is why, in China, it is called the "June 4th incident").

This is not Chinese propaganda or a conspiracy theory. Western journalists covering the protests back this interpretation of events. The Western narrative was manufactured later. If you ask on Lemmygrad's 101 community, someone less lazy than me will give you the sources.
