A few years ago, the Lemmy Developers decided to keep their political views on lemmygrad while keeping lemmy.ml more neutral. Now they are banning users who are critical of their actions and bigotry.
Anti-Tankie posts may put you at risk of being banned from commenting and posting on the lemmy.ml instance.
They chose to defederate because people kept dissenting against their abhorrent hate-speech.
No one is allowed in their community anyway, to post, you need to pass a vetting process.
That’s why this community and MeanwhileOnGrad exist, to highlight the extremism and bigotry. Nor is it cherry-picking when it’s posted by the admins and prominent users of the instance.
