I didn't ask the question, maybe you should learn to read. I merely commented on the uselessness of his answer which did nothing but rephrase the statement the question was about while adding nothing of use.
You would never tell someone to "learn to read" in face-to-face conversation, so you shouldn't here. Equally importantly: the comments you're replying to are productive; they are the actual answer to the question posed.
If someone told me to use google the way he did, yes I would tell him that in real life, except I'd say open your ears and stop being a duche. And no, the comment was not productive as it had nothing to do with my comment that he was replying to. It may have been productive as a reply to the guy who asked the question, but that wasn't me.
