It's not about having a "bigger stick". Those who fight for the rights of themselves and others are often the ones with the smallest sticks, and this must be cunning with their tactics, or blatant enough to get noticed and win people to their side. Any oppression deserves to be fought back, as a self defense tactic. If you scream about being a pacifist in the face of oppression, you are ultimately siding with the oppressor. Some readings:
Frankly, if you remain silent in the face of oppression, I wonder if one truly stands against oppression.
I'm a bit of a radical in this regard, also as a side note, the whole "do no harm" bullshit is fine and dandy when your opponents act the same, but if someone harms me, you best be sure I'm harming right back.
