6 years ago, a med school student friend had a really detailed powerpoint presentation showing actually, yes, drinking no alcohol is far better for you. I think this edge case benefit is just promoted by people wanting to feel better about their alcohol consumption, and not to mention pushed as a repetitive PR point by alcohol companies.

Maybe, but this works in reverse too. There is a bias towards assuming that behavior perceived as sinful must also be harmful. This manifests in bad science in any number of examples: meat consumption, fat consumption, and yes, alcohol consumption. The USDA food pyramid (1992 one) came out against sinful fats and guess what happened? A low-fat/high-carb craze that was completely ruinous to public health.
