You don't represent alcoholics. Personal experience gives you a bias, not a justification for being condescending. Medical decisions are not and should not be based on moral judgements of the patient's behavior.
You're now changing your idea to add "over someone who may need it more", which is different, and I'm not disagreeing with that. It's the same as favoring young or healthy people because they're likely to gain more life extension from a transplant when the rest of their body is working OK.
I assumed that was implicit given the context of the conversation (a comment up the chain discussing their uncle who got higher priority because he continued to make poor lifestyle choices). Obviously I'd still rather my liver go to the aforementioned alcoholic than into the ground, but they wouldn't be my first choice.
There was and is no condescension present. I don't look down on them just like I wouldn't look down on a 90 year old man whose liver is failing from natural causes. Neither would be my first choice for recipients of my liver.
