Yes, the comment about downvoting broke the rules, and yes the comment about Germany would have merited chiding if the author hadn't deleted it. But the HN guidelines apply to you, as to all of us, whether the other person breaks the rules or not.
Your entire comment upthread was uncivil. If you're sincere about abiding by the guidelines (as I hope you are), it would be an instructive exercise to rewrite it in a neutral, respectful way, editing out the nose-tweaking and every trace of snark. Do that on three or four occasions and you'll see how much better your contributions get, regardless of what you're arguing for. I know that sounds patronizing, but I don't mean it that way—it's a process that many of us, including me, have gone through, and it helps.
