This is Lemmy, not hexbear, beehaw or similar forums. I’ve had experience with other platforms removing “downvotes” (or their version of it). Sometimes it works, but oftentimes it doesn’t.
We can go a lot further into this discussion, but I’ll summarize my opinion as follows:
Neither having nor not having downvotes is “right”. They’re just different - and lead to different types of forums and discussions. I prefer the former, because in many topics that I want to discuss, they provide important feedback (both to me and others), even if you perceive that this feedback comes at a cost.
If you like, we can elaborate further, but I think it comes down to Beehaw ( & co.) and Lemmy being different platforms, which is a good thing. The world would be a very dreary place if everything was the same - and this is something that corporations are constantly pushing us towards.
