I certainly hope the comments stay wholesome too. Too many times I have seen posts in communities meant to be uplifting that talk about a bad thing getting stopped or repealed or what have you (fitting), and then the comments being super negative by talking about how the bad thing will just start again, or going super into how the bad thing got passed and in less of an informative tone than a doomer one (unfitting). They might be factually correct so I never downvote that unless positivity is actually in the rules, but it's still disheartening and counter to what I believe (but the rules don't say, so I don't report or downvote) is the purpose of the community, so I end up not participating.
Although I understand "then why not go make your own," I don't because I mod several communities already, don't want to go all Reddit powermod by adding even more (though I do think it would be a bit more forgivable on this newer social media where someone has to start the thing in the first place), and I've had less time for Lemmy as life picks up so adding even more Lemmy responsibilities doesn't seem smart for me.
