I happen to be on Twitter so you just called me a moron, Mark (as well as many other core developers).
While I think Stefan's response was uncalled for, he at least felt like the injured party and thus his response could potentially be attributed an impassioned response that should not have occurred. IOW while I understand why the reaction occurred, that doesn't excuse it while warranting a warning of that fact and that it shouldn't be considered acceptable behaviour overall.
Your response, though, definitely crossed a line as you were insulting as well as not directly involved in the issue at hand, which means you had no direct motivation to be upset other than to prove a point and be rude entirely on purpose. IOW you were just piling on the rudeness for no good reason.
For that reason, consider this a warning from me that this kind of behaviour is simply not acceptable. If it happens again I will request at least a 2 month ban for you from the mailing list.
