Maybe Bond, he's a casual day drinker which aligns with alcoholism. The frat thing is more about binge drinking than alcoholism, which is not exactly the same thing. Binge drinking can cause alcoholism in the long run, but is inherently problematic even if it doesn't reach the point of developing a physical dependence.

To some extent American culture does glorify binge drinking, but I don't think the same is true of alcoholism. People brag about how much they drank at the party last night, but they feel shame about starting the morning with a few drinks.

I’m fairly certain that the “odd” behaviour is that of the extremists who hijacked the original concept to promote the idea that being fat is good.

I’d consider calling it “odd” to be an understatement. I always thought such extreme positions were a bizarre denial of the negative impacts that obesity can have on personal well-being and quality of life. Having said that, I only ever encountered such views on the Internet; never in real life.
