John,
Actually the lesson here is don't say anything on the internet that you cannot, or are not prepared to back up. Because whether it in Hopkins or outside in the parking lot, or in one of the small hallways, someone might not enjoy the fruits of their labor.

Yeah, well some people excel at pushing other people's buttons until something is said that maybe they can't or don't really want to back up.
Do you really want a world where everyone is only saying things that they are willing to back up? If so then let's just go back to the wild west and everyone is carrying a gun. I think I might start packing one since you seem to think people ought to back up what they say on the net and I have received a couple death threats from people online.
The lesson is to not get involved with trolls. Eric chose to engage Larry and antagonize him and Larry went off the deep end and Eric made it violent in real life. Next time Eric does that the guy on the other end might just shoot him instead. That would be a tragic end to the story that began as two guys fighting on the internet.
