By community, do you mean just this particular Lemmy community or the community on Lemmy collectively? If the latter, there are other alternative Lemmy communities on other instances that may be better suited for you.
You mean “the former”. But this is a counter-argument that dares not speak its name. My proposition is that all online communities suffer when opinions are downvoted (which is how the downvote button is overwhelmingly used), not just this community. Just as all dinner parties suffer when someone points their finger at someone else and says, “Shut up, you’re wrong”.
