And just in case people don't feel like reading through the links.
Here's an announcement from lemmygrad themselves.
We’ll go through each account application with due diligence, but we would like you to know before you request an account that Lemmygrad is a Marxist instance, principally Marxist-Leninist. We like Stalin and we uphold the DPRK’s sovereignty and legitimacy over the whole of Korea. We love China’s Socialism with Chinese Characteristics
By experience, most internet users who self-identified as Communists and oppose Stalin tend to be either brainwashed people in countries that are under the rule of Westen European diaspora or trolling bots. Is there any real Communists who actually oppose Stalin? Stalin receive the most slander in Western European diaspora because he refused the destruction of USSR through an unsustainable war against Fascism and he forced the desolution of alliance by British and French empires with Hitler’s Nazi Germany. The Liberals complained about the non-agreession pact between Stalin and Hitler, even when the Western European empires forced Stalin to make the peace pact, that buy time for war preparation by USSR against Hitler at a time when USSR is too underindustrialized and too devasted from the Russian civial war that was more damaging than World War 1.
DPR Korea isn’t sovereign over the whole of Korea. Not yet, anyway. Hopefully soon.
Lemmygrad is/was hosted on the same IP as Lemmy.ml, which is publicly run by the head developer. Lemmygrad is very clearly owned by the same tankies that develop the platform.
