If I post a comment suggesting that xeromal's distaste for downvoting is because they have a tendency to post low-effort comments and generally not contribute to healthy conversation, would you just let that be, too? Perhaps you would, but many people might expect an accusation they consider untrue to be worth downvoting.
This is an Ask HN. People are generally expected to upvote accurate answers and downvote inaccurate answers.
An answer which includes false accusations of brigading, praises Musk as brilliant, and suggests that all dissension is due to politics is unhelpful, inaccurate, and worth downvoting. As I said before, I'd have downvoted it myself, but it was already sufficiently downvoted.
