I looked through all that stuff, and it takes a lot to shock me, but that did a pretty good job of it.
While I think it is possible to go way off the deep end in response to someone who has been baiting you and baiting you for a while and say something totally out of control (I've done it before; I'm pretty sure everyone's done it before), nothing that was said to him warranted that kind of vitriol. They way he reacted was like using a nuclear bomb to get rid of an anthill- yeah, it takes out the problem but you also end up destroying everything else too, including people who might have been on your side at one point.
