Without a doubt Spanking is a time-honored prerogative of parents. While there are some parents who spank inappropriately or for unwarranted reasons, that is no reason to take the option away from everyone else. Those of us who were spanked as children for correction and out of love do not commonly report being harmed or traumatized by the experience. A spanking hurts at the time, but it is only a momentary inconvenience. There is no justification for the state to invade the privacy of families by taking away the rights of parents to spank.
No they should not... Nobody should be tortured, period.
Communists should be executed if they have committed, and been judged guilty of, a capital offense by a competent authority--just like non-Communists. Simply adhering to Communism as an economic idea is not a crime, let alone a capital crime. It's a stupid idea, but so is creationism, and we don't kill people for believing in that.
