I'm not a pacifist, and so I guess I agree with you. 
Earlier in my life, I struggled to get to pacifism, and learned to distinguish between pacifism and non-violence.  I also accepted that the reason I am not a pacifist is that I am a sinner.  I recognize that the question "What would Jesus do?" can be trite -- but I also think it can be clarifying.  Can we do what we cannot imagine Jesus doing -- and still call ourselves Christians? Or asked differently, how much distance between Jesus' teaching and example can we rationalize and explain away? Father Berrigan was a more rigorous Christian than I am.
