Muslims only understand one thing. Whenever a Christian is killed or a church is burned, there should be massive retaliation each and every time.
Retaliation against noncombatants is against the ethic taught us by Jesus Christ. You can't honor Him by dishonoring Him.
On the other hand, it would be an act of civic virtue to hunt down these church-burning, murdering jihadi-aggressors and stop them dead. They should meet end which is swift, severe and certain.
