Because I read Alice Miller's book "For your own Good: Hidden Roots of Cruely in Child Rearing Practices" - I tried very hard to raise my sons without ever using physical coercion. I was pressured very hard with my first son into using corporal discipline with him a few times. Something I will always regret... But because of the support I got from my husband while raising my second son... we supported each other's choice to refrain from any kind of violence with him and he's just the coolest little guy. It's a myth that you need to use violence to discipline a child. It's just lazy parenting or ignorant parenting. I strongly urge people to check out the work of Dr.Alice Miller on this subject... She makes a very compelling case for why ALL forms of violence against children is wrong. I also found NOTHING in her philosophy of child rearing that contradicted Libertarian ideals and principles. Can't recommend her stuff more highly.
