I have a way with words, mostly because people seem to miss the point if it is subtle. A slap in the face will get attention, a polite cough is all too easily ignored. The OP has basically called the readership of Codinghorror worthless and incapable of contributing to a site so elevated as HackerNews and if we could only ban Codinghorror from HackerNews then perhaps this flood of proles could be thwarted (and how is that supposed to work exactly? Do we get an injunction to stop Jeff sending his readers here?)
I think you're absolutely right about rglullis's methods here, they strike me as pretty slimy. I also find the whole To those who have objections to the choices: I did a copy-and-paste of PG's poll when he was deciding whether or not to ban valleywag. just a weak grab at legitimizing his behavior through canonizing something pg did for a fringe case. All in all, rglullis is plainly taking this all very personally and trying to rationalize his reaction.
As for the "jerk" aside, well, it goes either way. You can either say something politely, knowing that most people who disagree with you will probably ignore you. Or you can say something more heavy that will get their attention, but then you'll have to deal with character assassination tactics like marginalizing you as a extremist or a jerk, etc. Either way you're kinda screwed.
And I'm the jerk?
