Not that I think Jourdan is guilty, but domestic violence is a bit different than sneaking into a club when you're underage.
The issue here is not that sin is sin, but that some sins are more grievous to society than others.
When I was young (12 years old) I stole comic books from the 7-11 store. Yes, that's against the law.
But am I being "holier than thou" because I criticize someone for beating his wife?
Sometimes, it baffles me how people use the "holier than thou" term outside a religious context.
