They have legitimate stalanists. Some are critical of stalin some, for some reason, support him uncritically. No one wants to discuss things in good faith with them even if they are respectful, just call them tankies. So why do they need to feel like they need to be bastions of debate? If you don’t like their community just block it.

I’ve never used obsidian but the people who make thousands of anki cards, release them for free, and allow the community to add important ones of their own has saved me many times.
