Does the reddit style format breed toxicity?

Does the reddit style format inherently make for a toxic environment? Or is it a culture of toxicity from the influx of reditors? For lack of a beter example, on stackoverflow, when someone down votes you, it comes with a comment saying how to improve. On mastodon, people can't downvote you. These platforms are a joy to use, lemmy is depressing if you post. Its depressing because every post or comment, no mater the quality comes with downvotes, and usually no criticism to accompany it, you are left not knowing if youve made a mistake, or if its just trolls, bots, or idiots. At the end you feel insulted not improved. What do you think?
