Every day I see the top comment in a thread being a typical middlebrow dismissal, the type that adds nothing to the discussion. With that in mind, it&#x27;s really surprising to me that this comment was downvoted. Before I upvoted it, it was grey, and after I upvoted, it was still grey. Who are these people who downvote a perfectly good comment like this? It puzzles my mind.<p>At the time of writing this comment, at least 10 comments in this thread were grey. There are a lot of comments in this thread being downvoted for no particular reason - moderators, what&#x27;s going on?
