I know what you will be saying, and I know what you mean.
Just because it isn't personal doesn't mean that these people are
not dangerous. Off course they are all potential killers, but
usually only if you engage them and play the game that they
want to play. The majority of the time these situations are
benign until we counter their initial aggression, either because
of our ego, some misdirected need to cleanse the world of bad
people or the fact that we are reacting to the situation in a
displaced manner ourselves. Imagine two guys, lets call them
Joe and Pete, beating the crap out of each other over a minor a
traffic incident. But they are not really fighting with each
other. Pete is really battering his bullying boss and Joe is really
battering his domineering wife. When they end up in court
together neither will really be sure why they were fighting in
the first place.
