Like I say, had this been about a Christian parent, you'd be posting something very different. You certainly wouldn't be saying what a great guy he is that he he tucked tail for the sake of getting along. What he's going to find is that people like you don't really have respect for him. You know he'll back down when pushed and you want to encourage that. Certainly you'd never back him up should ever decide not to apologize and walk on egg shells. Like I said, it's all hypothetical anyway. That'll never actually happen so you've trained him well.
