The sorting algorithm seems like it needs a bit of work. I don’t have the issue that I see month old posts, I tend to see very new and not very upvoted posts instead, but that’s fine with me. I just saw your post on hot near the top page, for example.
Did you even bother to read the sidebar and rules before you joined lemmy.world?
Lemmy.world doesn’t allow for discrimination, racism, homophobia, transphobia, etc. It doesn’t even allow for name calling and requires posts with controversial topics to declare that it is a controversial topic… In other words, most lemmy servers, especially the lemmy server you have chosen to join, have much stricter moderation rules than reddit, twitter, etc…
If you don’t want “snowflake crap”, you should probably join another instance, or host your own server where you make the rules… And you are free to do so, but demanding that a server, which you don’t own and have no control over, panders to your specific wishes seems a bit entitled…
One could even say that your attitude seems a bit “snow-flaky”…
