Lemmy.world is the community you are a part off, its also the community the meme example i shared on.
A community is not the same as a subreddit but as a tiny full reddit. Its run by admins who set rules and standards for the entire server they own and with tends to come sort of ideology. When you go to lemmy by default you will see the frontpage of your community only.
@memes, @technology within a community are call places but i don’t like that naming. They are like a subreddit and i find they actually have the strongest community feeling and guarded ideologies. They are much smaller so if you see double standards within one of those its usually a sign of an echo chamber. This was not such a case.
Theres also the fediverse. Which is all lemmy and related servers that are federated. This is the bigger lemmy community that curates what gets to the front page of “all” because most of lemmy is progressive and safe for minorities other communities servers that openly welcome nazis and c-abusers have been defederated so they can no longer see or interact with eachother. If you both comment on the post on a neutral server then you wont even see eachother comments
Its very likely that at least one of the People upvoting you saw that meme 2 days earlier and thought “yeah they only care when they are affected, which is obviously wrong and i would never do it” simultaneously id expect people who felt really strong about that meme to be perceptive enough to recognize it in your comment and downvote it. (No offense) but because it was about Facebook, many peopl on lemmy dont have facebook. We all passionately hate it. You basically got people agreeing against their own ideology, which is again normal but does weaken that ideology.
Progressives like me should strive to care against that are wrong no matter if its us or someone else. I am not from ukraine or palestine, i dont have family or friends there but i know people are suffering and i want a better world for them, likeways i want the boomer population on facebook to have a better world where there data isn’t routinely stolen by Bigtech.
