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.
Yes, most people here probably know that. But it’s really got nothing to do with the actual point being made. You’re just declining to engage. Of course, the idea you’re declining to engage with is kind of dumb, so one wonders why you didn’t just walk away.
