You see proponents of both views engaging in egregious argumentative practices at times and it is clear that this situation is continually degrading and needs something to be done about it.
Does it? I'm kind of thinking if people insist on browsing Lemmy in All mode, and forcing themselves to view everything they they don't want to view, then it's on them to learn how to block communities in their own profile settings. Or if you want to help them somehow, maybe some way to display a quick how-to to show people how to block communities and/or browse in Subscribed mode could be useful. Just not sure how feasible that would be overall if people are browsing All and just reacting to things they don't want to see.
For me browsing Lemmy in Subscribed mode and purposely subscribing to communities I'm interested in works well enough, no need to wade into the for/against AI drama or any other topics I'm not interested in.
You forgot to mention their Tor link, seems to be working fine http://l337xdarkkaqfwzntnfk5bmoaroivtl6xsbatabvlb52umg6v3ch44yd.onion/
