That’s the kind of thing which addicts say to justify their lifestyle.
If you have a problem with people who don’t drink, consider them to be second rate friends, then you absolutely do have a drink problem.
There have been several studies where people have been led to believe they’re drinking, or in the company of people who are drinking where in fact there is 0 alcohol in the equation, and they have behaved accordingly, even believed they’re drunk, and then it turns out they’ve been drinking non alcoholic all night.
The people who judge others for not drinking seem to forget that alcohol is an addictive substance. It is responsible for countless health conditions, obesity, heart and liver disease, alcohol ruins lives, and if you’re not addicted now you’re on the road there.
If you need alcohol to feel enabled, and more to the point if you feel that you can only be friends with like-minded drinkers then it’s a short leap to being entirely dependent on alcohol. You already feel that you’re not yourself without it. That says everything you don’t yet want to admit.
It’s one thing to say that you’re not bothered about giving up alcohol yourself, that you enjoy a glass of wine so don’t feel you need or want to.
Relegating your friends and judging them for doing so is on the problematic scale of drinking.
And for the person who compared it to skiing, it’s not remotely comparable. Skiing is an activity, people go on skiing holidays, therefore it stands to reason that they might not have that in common should one of them give it up.
Drinking however is not something you have to do, you can go to the same places, do the same activities, have the same conversations, and you don’t need drink to do it.
