"If you downvote, add a comment (why?)" That seems to be what kyro did. A one liner simply doesn't add much to the conversation - as you said, it's a fine line. He seems to have been overly critical and could have reigned it in a bit (no need for "childish, baseless", etc.). Points on both sides. Seems to boil down to this: Post thoughtfully, and critique kindly. Easy enough.
