Jesus did twice justify "murder" of children that cursed/hit their parents in the New Testament and shamed those that were against it as the O.T commanded. Are you ashamed of it.
* "He who strikes his father or his mother shall surely be put to death." Ex. 21:15
* "Why do you also transgress the commandment of God because of your tradition? For God commanded, saying... `He who curses father or mother, let him be put to death.' But you say..." Mat. 15:3-4
* "For laying aside the commandment of God, you hold the tradition of men..." [Jesus] said to them, "All too well you reject the commandment of God, that you may keep your tradition. For Moses said, 'Honor your father and your mother; and 'He who curses father or mother, let him be put to death.' But you say..." Mark 7:8-11
We are not to do this vigilante style, but give place to wrath (let the government authorities do it)... but Jesus was not one bit callous about the death penalty.
You could make a bumper sticker out of that. "Whose Ass Would Jesus Bust A Cap In?"
Every reference you use is speaking of adult children. No wonder people get the idea that Christians are nut logs when a character like you seeks to use the bible as support for the murder of a 14 year old.
I think Islam is where you will find welcoming arms.
