You don't beat up somebody for being stupid. You don't kill somebody for advocating planar planetary physics. You don't beat up somebody even for advocating racial discrimination. (You don't "quietly demur", either. You respond with forceful denunciation and moral condemnation.)

In this country, you don't beat up or kill someone for blasphemy. And in any country, you don't if you're a Christian. A Christian's orders are to love their enemies, do good to those who hate them, and pray for those that persecute them. I don't see "kill" anywhere in that.
