As Alinsky stated in his thirteenth, we are to pick the target, freeze it, personalize it, and polarize it. But there is a caveat. This is a valuable principle, but we have to understand it in a Christian context. Because of the cross of Christ, it is possible to distinguish a sinner and his sin. This means that your adversary might wind up repenting, as Saul of Tarsus did, and if you have trouble with that possibility, you are being vindictive instead of being principled.
