You're missing the point. You can disagree all you want, but do so in a way that contributes to the discussion. Sarcasm rarely does so, and is generally frowned upon. So too, for that matter, are ALLCAPS and such rejoinders as "blah blah blah"

No, you're missing the point. I showed my initial disagreement with harmless good humour. Too bad you didn't understand that, and decided to give the same condescending boilerplate "HN is just different" speech I've seen others be berated with a dozen times.

There's nothing wrong with "harmless good humour", and there's definitely a place for it. HN isn't that place, unless it adds to the discussion. Most HNers don't want it to turn into reddit, where comment threads are filled with such harmless good humour and very little content, and so will downvote it.

I'm not trying to berate you or be condescending. I'm just telling you why you're being downvoted, and why such comments will continue to be downvoted in the future. It's up to you to do with that information what you will. If you choose to take that as condescending, then I apologize for the offense.
