I downvoted this because the guidelines [1] specifically state "Don't be snarky." There are plenty of outlets for snark. I like HN for thoughtful replies, even when I disagree with them.
I wouldn't classify the comment I replied to as egregious. I can't find in the guidelines where it mentions not discussing downvotes. Perhaps you could cite that, specifically.
