By default, Lemmy allows downvotes globally. However, when a server disables downvoting, it is similar to using a feature that is usually reserved for enterprises and very small, non-federated communities.
If a user prefer to not see downvotes, they can disable it by his favourite client settings, but the rest of the community should not miss this functionality for the pleasure of few users.
Well i think caring about upvotes and downvotes at all is the sign of someone going through an exceptionally fucking lame part of their lives. Just stop giving a shit about something so… so… extravagantly useless and bam! Life improved.
Upvotes and downvotes are simply engagement markers that prove you made an impact on that many people. If you need to tell someone you don’t like them, ya can’t downvote them, tell em! Tell em how wrong they are! Get that bag baby! Now get up, get out there and get ta arguin with your words
