Patterns of Behaviour
So Arnold is a chump with an ego the size of Manhattan. He's the Alpha of an alpha male, no doubt trying to score by being rude. Can't say I haven't met anyone like him in my long life.
If he gets in, I doubt he'll change his behaviour. If anything it could get worse, and cause another scandal. This guy is hard wired, and although HE may think it's all in fun and jest, he has crossed the boundaries of what is civil and courteous in what he considers a meat market.
No wonder the women he groped or embarrassed called him on it.
