Do you (or would you), love your child any less once you've disciplined them?
I wouldn't kick him out of the house and tell his siblings that he is no longer welcome there. I wouldn't send a letter to his school telling his classmates why he's no longer welcome at his father's house. That's what I wouldn't do.
Good point. Apparently, some can't/don't/won't differentiate between discipline and hate. Or, between a criminally insane killer and a political, calculating judge.
