Maybe it's a generational thing (born in '92), but Graham often seems to paint a picture of nerds similar to what you might see in movies and TV shows depicting the 80s, like the kids in Stranger Things.
Even this article, while I can certainly conjure which of my friends growing up were the "fierce nerd", it still feels a little disconnected from my reality.
For example, Graham begins by explaining that the concept of a fierce nerd is one unknown to the general public. But I'm not sure I agree. In the era I grew up, there was not so much social distinction between who is a nerd, but there was a lot of social distinction for those who were argumentative, or "fierce". In my experience, everyone knew who the "fierce nerds" were (although not by that name), because they were known for their awkwardness and combativeness - not for their nerdiness. Indeed, my own nerdy friend circle in high school spanned a wide range of popularities and I would say "fierceness" (or rather, lack thereof) was probably the best indicator of popularity.
I see these themes spanning Graham's other musings on nerds, typically trying to characterize a class of kids who are hated for their interests and passions, but that's just never been my experience. I think it's a generational thing.
