Mr. Nugent, the father didn't "clash" with his kid, he tortured him. Just because Sean did't turn out to be an obvious cripple doesn't mean he wasn't abused. Perhaps you think that there is only one way to energe from such abuse (i.e. as a basket case), and that if the kid has a strong enough ego and strength of character to endure this abuse it's somehow acceptable or okay since there was no damage.
By the way, I want to make it clear that the Jim Nugent to whom I respond is not the Jim Nugent who is publisher of Golfweek.
