This is for any apologists out there, but particularly Losing:
Adults choose their behaviour. No-one else, adult or child, is responsible for what behaviour they choose or what course of action they decide upon. Whatever they say or do is 100% their responsibility, and, if it has a negative effect, they are 100% to blame.
Whatever a parent does or say to the other parent cannot force them to disown a child, to walk away from them. Nothing that anyone else in the whole wide world can make them do that. Only they CHOOSE to make that decision.
Even if a parent was pushed to the very edge of their limits by another person, to tell a child you are disowning them (and for such trivial reasons such as not sharing his interests - colossal narcissist, much?!) just destroys them and it is an entirely selfish, egotistical, despicable act that naturally disgusts any normal person. Only a deeply disturbed, terrifyingly self-obsessed cunt without an ounce of even the most basic empathy, caring and understanding could choose such behaviour.
Oh, yes, and trying to blame someone for another person's failings instantly makes your participation into any normal, rational, decent discussion null and void, because not only is it plain old nasty and wrong, it is the argument style of a small child and such a person is clearly incapable of conversing about the adult world in any meaningful way.
