WTF? You wouldn't say the dad's a piece of shit? I think the majority of people in this day and age would disagree with you on that point after watching the video.
It's not just that he's spanking his daughter. It's that he's doing it in anger (pretty sure I heard him say, "Bend over or I'll hit you in the fucking face") to a girl who is 16 years old. What the hell kind of person is he trying to raise?
If anyone deserves a beating, it's the father. He is definitely a POS.
It depends which "majority of people" you were talking to. There are geographical and cultural differences when it comes to corporal punishment. What some people think is abuse, others view as normal. The kind of discipline you saw in the video has been and is being used by parents since forever.
Disciplining in anger isn't abuse either. Some psychologists actually advocate that you do it in anger (without abusing your kid).
I didn't discipline my kids the way this guy did, but I'm not going to judge his methods. I know way too many good parents who used (and continue to use) that method.
But times have changed. I remember the principal and vice-principal at my school having a paddle hanging on the wall, that they actually used. Today, that would land him or her in jail.
