Most pacifists react to this issue by simply pretending that it doesn't exist,- that Muslims either never deliberately choose violence, that violence always stems from earlier violence, poverty, or injustice, or that if people do deliberately choose violence, it's in rare cases that are not really of great importance. But history abounds with Muslims who have deliberately chosen violence. The ease with which Muslims from non-violent backgrounds have been induced to commit atrocities shows how easy it can be for the violent to recruit assistants
How do we respond to people who have opted for violence?
Appeasement merely reinforces the conviction that violence gets results. Moreover, it provides gratification by reinforcing the feeling of dominance. When confronting people who have already opted for violence, non-violence has a very good chance of perpetuating the cycle of violence. Retaliatory force, on the other hand, makes the results of violence a lot less simple, a lot less effective in getting results, and a lot less gratifying.
