I didn't say that being drunk was making Billie right, I tried to imply that a bunch of Internet users need to let the whole concept of THEM being right go in cases of serious substance abuse. It's somewhat uncomfortable to dissect one person's personal struggle to the point of being right or not, knowing what was going through his mind and what wasn't.
My cousin almost killed my aunt and he got to the point where he was sent to jail in December, for only six months and only for the attack where he randomly fired an illegally-owned gun, so I know what I'm talking about. I might be straight-edge myself, but I've had my own share of alcoholics.
The "true character comes out" thing is applicable only for people who live pretending and who then, well, don't pretend. Otherwise, a Mr. Hyde kind of a persona comes out. In cases of downright psychotic people (my cousin is one of those), they get violent. And I have solid knowledge of psychology, far further than popular myths quoted here.
halfempty, I'm really, really sorry that you're going through this with your dad.
