I like you very much, John, but I don't like that kind of behavior.

You mentioned passive-aggression. The truth is that raging on an internet messageboard is one of the ways it shows. One of the main features of passive-aggressive behavior is a tendency to try to make others angry, to frustrate others and to pick fights. Thats what you've done in the Dungeon more than anything else. If you wanted to do something productive, you could do political work in your local community, fund a lawsuit to change things, something like that. But arguing and insulting your friends isn't cool. That won't help anything. If you wanted to vent, I could understand. But that doesn't include attacking people that have been your friends.
