Platforms like Voat have disgustingly promoted fascist ideologies in the name of “free speech”, but that doesn’t excuse leading members of Lemmygrad, Hexbear, and Lemmy.ml from their persistent history of supporting Russia’s illegal invasion of Ukraine, supporting Chinese totalitarianism (not even true communism) over Taiwanese democracy, and disgusting transphobia.

1. These 3 instances support the people of Donetsk and Luhansk, which is the standard communist position globally.
2. The PRC is a socialist country, public ownership is the principle aspect of the economy and the working classes control the state. At a democratic level, local elections are direct, while higher levels are elected by lower rungs. At the top, constant opinion gathering and polling occurs, gathering public opinion, driving gradual change. This system is better elaborated on in Professor Roland Boer’s Socialism in Power: On the History and Theory of Socialist Governance. Taiwan, on the other hand, is largely controlled by capitalists, and despite their claims of being the rightful rulers of all of China, almost no countries recognize it over the PRC.
3. All 3 of those instances are some of the most trans-positive and friendly instances on Lemmy. The views of Nutomic do not represent the views of the average user, this is confirmed by anyone spending any time in any of the 3 instances you listed. Communists are pro-LGBTQIA+.
