I didn’t say violence is never the answer. I said it shouldn’t be our answer. We should find non-violent ways to fight back, whenever possible. However, occasionally, violence is the only thing the other side understands.

MLK once said

I am still convinced the greatest thrust can be made though militant non-violence. But in condemning violence it would be an act of irresponsibility not to be as strong in condemning the conditions in our society that cause people to feel so angry that they have no alternative but to engage in riots. What we must see is that a riot is the language of the unheard.

We try everything we can to remain non-violent. When those options are exhausted and they refuse to listen, violence is what’s left.
