FediTips and the commenters in that thread make some good points. The fact that this Lemmy instance federates with Lemmygrad (which, if you look at the front page, is full of denialism about the Uyghur genocide) is an atrocity.

And yes, https://lemmy.ml/modlog does indeed have some questionable entries, such as:

• Removed Community conservatives reason: No conservative communities
• Removed Community Libertarian, in the pursuit of a free society reason: No conservative communities allowed
• Removed Community Conservatism reason: No conservative subs allowed

I created the Conservatism community, not knowing that Lemmy (lemmy.ml) became a leftist instance. (Lemmy was not explicitly leftist when I made my account in July 2020. Look at this archive of the front page from November 2020, which does not include the word leftist in the sidebar.) Fine, whatever. But, removing the Libertarian community with the rationale “No conservative communities allowed”? I don’t understand that. That’s not even politically accurate.
