One, if that's a point-by-point rebuttal, it's an extremely poor one (since he didn't cover all the points). It seems much more likely that he was quoting for reference. Two, there's nothing wrong with making a point-by-point rebuttal of an argument. It may not be the most elegant way to make a counter-argument, but it's certainly not as frowned upon as you seem to be implying. Lastly, please grow up. Piecemeal responses may impress no one, but vicious and petty comments like yours only serve to lower everyone's opinion of you. Find somewhere positive to vent your anger, please.
