It wasn't an argument, it was a dismissal.

I noticed the tendency on LW to portray comments as attacks. They may seem that way to trained rationalists and otherwise highly educated folks. But not every negative comment is actually intended to be just a rhetorical device or simple dismissal. It won't help if you just downvote people or call them logical rude. Some people are honestly interested but fail to express themselves adequately. Usually newcomers won't know about the abnormally high standards on LW. You have to tell them about it. You also have to take into account those who are linked to this post, or come across it by other means, who don't know anything about LW. How does this thread appear to them, what are they likely to conclude, especially if no critical comment is being answered kindly but simply downvoted or snidely rejected?
