Agreed. I only downvote if the comment is truly offensive, purposely unhelpful, or an obvious troll. Unfortunately, as you mentioned, old habits are hard to change. Everyone will have different opinions, and communities are a means of expressing them. As a whole, I believe the fediverse is trying to foster healthier conversations than other social media platforms which often encourage toxicity.
Thank you for bringing this subject matter to light.
