You are quite right in regard to dictionary definitions. I used it as it is something you often do especially in regard to your google cut and paste. It's OK to use when it suits your arguments but not when it fails to correspond to the "changing and evolving zeitgeist" that may happen to be your flavor of the month.
When one defines Pacifism as say an opposition to war what does that mean? I take it to mean that one is oppose to war -- all war. Of course some may take that to mean that they oppose war except for the times when you have to fight them. You say pacifism, i.e., non violence, is superior to aggression. So do I, and so do most people, though most people don't consider themselves pacifist. How do we differ? Again, to repeat a previous question, how does your pacifism differ from what most people believe since you don't believe in force except when force is justified?
BTW, I'm at work and my responses may be haphazard.
