That was to be my claim, but....well, read above.
Ahhh, then we're somewhat in agreement.
That being said, there is somewhat of a disconnect between nerd and geek stuff in general. I wouldn't class video games as geek or nerd culture, because everyone in the West and East plays them to a certain extent. And hell, whilst Magic was considered niche when I was in school, 5 years later you had pokemon and pokemon cards, and it seemed like every young child had them. This may be confirmation bias, but it certainly seemed that way to me.
Anime .... well, see there seems to be anime and
anime. Like I don't really watch all that much, particularly now. But I love Spice and Wolf (Manga, anime and light novels) ... and I would think the majority who have seen Akira are probably not heavily into anime, but it's an awesome movie. So I think for at least half or more people that watch some form of anime, most people are only going to tell you at most 40 things they've seen ... and they could only likely name maybe two or three big name anime production people.
Like I doubt anyone with even a fleeting interest in film hasn't heard of Miyazaki.
And the list kind of goes on.
I'll give you a completely subjective idea of some of the big things in geek culture that I think is firmly entrenched.
Cosplay
Tabletop gaming
Trading Card Games
Niche consumption anime (up-to-date with what's on in Japan, obscure anime from the 80s, basically anyone invested in it)
Old Doctor Who (Unless you're British or Australian, the old Doctor Who didn't really find popular consumption)
Trekkies
Comics
Monty Python (Beyond the movies)

There's probably a ton more that I can think of, but some basics off the top of my head.
The thing is that these geek past times are not exactly conducive to fostering some form of intelligentsia within these cliques that identify with a lot of aspects of geek culture. If anything, a lot of it would probably dumb down your intellectual faculties if you were to obsess over them. If you ONLY read comic books, I don't think you'd be as worldly or wise as someone who has read all the literary classics, and converses with clubs and in university circles about their various social, historical and philosophical connotations.
I don't mind a lot of comic books, kind of digging Angela: Asgard's Assassin and Colder: Bad Seed. But as fun as I think they are, I'm not going to lie and say that they deserve to exist AS MUCH as anything from Dickens. As much as I enjoy Spice and Wolf, I'm not going to say that it is on par with anything by Soren Kierkegaard.
I also think it's entirely broken to compare the two, because both of them are not trying to achieve the same goals and as vehicles of entertainment and storytelling I think they are both effective. But at the same time I'm not going to pretend that both of them will have equal impact on the progress and culture of humanity. I don't think geek culture is inherently good for people ... but I would suggest to people to pick up philosophy, or the works of Dickens.
So the idea that nerd and geek culture draws in intelligent minds because of inherent intellectual faculties necessary for entry... I think it's garbage. Particularly given that various things considered geeky or nerdy are things capable of wide reception by the public, now.
(Edit) I will also say that I was at one time big into cosplay (and other 'geeky or nerdish' activities) back when I hadn't really cemented my gender identity, kind of a social outcast. I will also note that due to Klinefelter's and other conditions, I'm barely able to function without concentration and singular focus. It took me thre times reading in quick succession the books of Sartre, Kant, Plato, Kierkegaard, Hegel, Wittgenstein and more to even soak in.
Without resorting to Sternberg's triarchic theory of intelligence and Gardner's multiple facets of intelligence theory, and all that, it's safe to say that I'm probably retarded in terms of a flat examination of 'raw' intellectual processing. Given that if I can't focus, my mind goes blank. But I was still able to achieve academic success in multiple branches of tertiary education. Was even offered a place to study at one of the best research universities in the world.
Intelligence is definitely not a barrier to understanding aspects of geek and nerd culture, or in its participation. As the OP puts it, I would definitely cerify myself as 'legitimately stupid' ... the saving grace of this is that I'm nowhere near as hindered as a person who is 'legitimately genius' and thinks they have all the answers.
