If I was walking down the street with a $20,000 ming vase, and you were running around nearly hitting me, I'd probably swear at you. Likewise, if you were running around on the street wielding a sharp katana, I'd probably swear at you.
A car is both as expensive as a ming vase, and as deadly as a sword. The idea that a rational person would not get highly upset when somebody threatened both their life and the most expensive thing they own is absurd. "Distance" has little to do with it.
Speaking of incompetence, there is a third type of troll. These trolls manner of speaking is seen as hostile by those who come from a more genteel social milieu. For example, in person as on the internet, they might tell you to STFU, or use words like shitpump, yet be trying to make a point in a friendly and helpful (perhaps playful) way. You need not be an egghead to be abrupt. For an insight into this social milieu, see an episode of Trailer Park Boys. People need to learn to function differently on a forum, because it is a different social environment.
Cars give people that, guns give people that, web skills give people that.
