Why Won't We Riot?

I've been thinking about Abdul Rahman a lot today (see Joe Carter for an excellent commentary). I was thinking that (and I pray it will not happen) if Abdul is executed for his conversion, Christians will not burn down the Afghanistan embassy or riot in the streets. Why won't we riot?

At first, I was thinking that this would be a reflection of our Savior's admonition to "love your enemies"(a la Piper's excellent commentary on the Muslim cartoon-rioters). But, Piper points out:

On the one hand, we are grieved and angered. On the other hand, we identify with Christ, and embrace his suffering, and rejoice in our afflictions, and say with the apostle Paul that vengeance belongs to the Lord, let us love our enemies and win them with the gospel. If Christ did his work by being insulted, we must do ours likewise.

The attention that the persecuted church gets in the American church is smaller than it should be. I rarely see the "grief and anger" of which Piper speaks, which leads me to a frightening question. Is the reason that American Christians will not riot in the streets because we are leaving vengeance to God, or is it because we are too engrossed with Survivor to notice Abdul's plight? The right response should have the right motive. Are we trusting God to judge? Or, are we just too lazy to care?
