However, it DOES remind me, in general, of the way a lot of *younger* people act - “I’m an xyz, look at me doing my identity! I buy from ThinkGeek! Do you?”
”Here I am, playing Magic: The Gathering! Because I’m the kind of person who plays Magic!”
The characters may be Gen Xrs, but they're written in some ways more like Millennials. I see this on lots of other shows - the characters saying things like, "I'm that kind of guy," or "I'm the kind of person who likes xyz." I see a lot of Millennials do this! In virtually every group. (See, the purpose of this post is not to debate the merits and flaws of Big Bang Theory.)
But it doesn’t mean that the people who do it are less authentic as whatever their identity is, it means that I just see lots and lots of younger (Millennial) people feeling the need to openly and loudly brand themselves or announce what they’re doing.
It’s kind of strange to me as a Gen Xr. We didn’t broadcast everything we did, at least, most of my friends didn’t. We didn’t think about what it meant about our identity that we did anything, the way that Millennials and younger seem to.
But it seems to be a big thing that I notice in Millennial behavior that I can’t unsee. I even see a few older people picking up on this: my mom constantly asks me, “what impression do you think I made?” or “what group do I seem like I belong to?” and even, the other day, “so, am I a hipster?”
(I haven’t observed it so much with Gen Xrs, but most of the Gen Xrs I know right now are kind of in a social hole with either work, childcare, or elder care, and are not really part of the same kind of social whirl the way that the younger people and retirees are.)
It’s not a bad thing, not a good thing, just a thing. For whatever reason, the culture presently asks people to do this, to identify what box they fit in. I don’t know why, but… ok. It’s a thing.
