It's easier to choose and curate for oneself. Blocking comms actually works (even if blocking instances or users doesn't). I don't see any tankie comms anymore, even if I still have to argue with .ml users in comments on other threads.

And even though mods can ban from communities or instances, no automated admin bots can give you a site-wide ban over petty reasons. I can say I hate nazis without getting my entire IP banned for "hate speech"...

Lemmy does seem to have some insular thinking (just like all social media communities). Feels like you can actually have discussion and at least learn why people hold those views instead of just being chastised.
