There's a big difference between a spanking, and a beating. I was spanked as a kid. I dunno if I would spank my own kids, but I wouldn't really look down on others who did spank theirs, it really depends on the kid and the parents and the situation. I think some kids really are sensitive and smart enough that just talking to them can be a good deterrent, and likewise there are some really thick headed kids out there that don't get the message without a spank.
That said, All day doesn't "spank" his kids. He fucking abuses them. Guy is a fucking moron. I don't doubt that his "spankings" are really violent. He's a fucking football player, why the fuck does he need to bring an outside object into discipline? Last time he did that, he fucking cut open his son's ballsack with a stick. Fuck that asshole. He's the same dumbass who chose OU over UT, so his decision making has always been suspect.
