I don't know what everyone is getting so menstrual about. He isn't doing anything wrong (Assumably). Nothing wrong with liking younger people, it's just a sexual preference and you don't get to choose them. Even if he was a pedophile (Which this hardly even classes as) then it's not something that's his choice, it's like being gay/bi/attracted to fat people/thin people/Asians/whatever else you can think of. There's nothing wrong with it so long as he's not actually doing something wrong to the underage kids.
