I'm part of what the author (weirdly) calls "thirteeners." I don't enjoy any of the stuff you list, nor do I even know anyone in my age group who claims to. Obviously lots of people in my "generation" do enjoy them, but there are also lots of people who don't. And those who do and don't can be found across age groups. I just don't think "generations" (as opposed to age, or religious intensity, or whether you are married with kids, etc.) is a very useful way to think about how Americans are different.
Some baby boomers did see themselves as some sort of revolutionary vanguard, of course, but that was probably part of the problem.
Yeah.... Low-carb beer sucks.
