When did I ever claim what I was describing was the majority? The entire point of my comment was to point out that bias is relative. Of course what I was describing is a microcosm. So is the "left wing bias" you described upthread. Hacker News consists of numerous microcosms. Of course you only consider one side to be an echo chamber, and yours to be "legitimate critiques." Which apparently I'm ignoring, despite you not having provided any, of anything. So it goes.
I won't belabor the point because I suspect most of the effort you put into my comment went into copying and pasting it.
