I don't believe this.
I got pounded pretty good by a 6'3" 200lb father up to the age of 10. He believed that it was important that I not grow up as a "Mama's boy."
In the end, I grew up as a "Mama's Boy" anyway!
I've never hit my kid, but I'd sock him pretty good if he tried to kill himself by running into a street full of cars in the example given by Jim Sangry.
My father didn't explain his beatings like Jim Albertson's Dad did. That sure would have been nice! But I knew I was bad when he hit me.
Dad did this when he was in his 20s and stopped when he was around 35. I think he just had a hard time dealing with marriage and kids after a rough day of work.
I think he hit me out of anger when his temper was short; but I also think he hit me as a proxy when my Mom screamed at him for something.
He was also a warmhearted father and gave me hugs as well. I don't think I carry any scars from the beatings. He never punched me, but he slapped full-strength. Ouch!
