Who are you responding to? I can't see where anyone is insisting that everyone else should change.
Generally when highlighting problems, you want them to change...
I mean who is like "Oh you have a drinking problem, just keep drinking, it's fine, I dunno why I even brought it up"
I've been around alcoholics, one night I bought a case of beer and had a couple beers while coding, then I got a talk from my girlfriend in AA about how drinking alone is a sign of alcoholism.
Startups don't have a drinking problem, alcoholics have a self-control problem.
What is assholish is to insist that everyone else change what they enjoy just because you don't like it.
