It sure can be. I've witnessed many instances where naughty words and raising your voice is very aggressive.
You're a delicate little flower, aren't you? But whether or not we class it as aggression, it is not the sort of aggression that warrants an armed response.
From aggressors. Are you not following? You confront some drunk thugs at a party and instantly you're surrounded by them telling you to fuck off. You pull out a gun as a defense to get yourself out of the situation. You get followed out into the street by three drunk mean who have now attacked you and taken your camera. Stand your ground law says you can shoot and you don't have to back down.
But that is not what happened.
