Perhaps I'm missing something, but it reads like a predictable rant to me, the kind of comment that destroys thoughtful discussion rather than supports it. That goes against the kind of website we want HN to be. Of course a good paint-stripping rant can be great fun (or outraging, a variant of the same), and there are other kinds of website for that.

Plenty of kinds of critique don't have this effect, and most HN users have no trouble practicing them—it's mostly just a question of wanting to.
