I would say the issue is also that those do drink are protective about their habits. They get quite defensive about being judged and will respond strongly to any threats they perceive against their drinking habits. This is characteristic of most addictions. It becomes a part of the personality and therefore it can be difficult to separate the action from the person.

The same would be true of those who enjoy gaming or own cryptocurrency. At its best, we're talking about a sort of tribalism. Human psychology is complex, and our relationship with alcohol isn't completely unhealthy.

The same can be said about vegans and anti-alcoholic, so what should we say about those? Maybe that people react negatively when being condescendingly criticized?
