What tone? He said you should read something before arriving at conclusions about it. He didn't add "you moron" to the end of it. And, it turned out, you hadn't read it.
Every criticism stings. They sting me even when I'm confident that I'm right, and even though a Markov 'tptacek could probably get 1000 karma points pretty quickly on HN. Don't confuse the sting of a critical comment with a breach of etiquette.
Say 'Why didn't you just X before jumping to conclusions?' out loud and tell me it's not rude. It also presupposes that my only reasonable response would be to read the whole report and criticise its contents, whereas I suggest you can criticise it from the point of view of who it is written by and the fact it's not a scientific article. I also clearly stated that I just didn't know. Why that justified that kind of response I don't know.
You probably find it less rude as you clearly have more of an issue with people not reading things than the issue at hand. On that point (unless I'm mistaken of course), let me point out I am happy to read TFA and do so all the time, but a 20 page report which I am simply not going to be able to reasonably assess is not quite the same thing, is it?
