Quit being the shit-stirrer (old-timey term for passive-aggressive) who provokes others. People wouldn't have "anger issues" if they weren't surrounded by idiots pissing them off.

It sounds like OP left out something important in the story. If HR told them to stop the passive-aggressive tactics, there is much more to this story. I do not condone violence, threats of violence, or shouting in a personal or work relationship. On the other hand I have known a few infuriating passive aggressive people. One of the biggest problems with passive aggressive people is you can never bring final closure to a disagreement. You may think you have reached a compromise only to latter find they are back with the same tactics on an issue you thought was resolved.
