Yeah. I think the nerd archetype fits more neatly into a framework about toxic masculinity reproducing itself even as it necessarily excludes large swathes of men. Like, for all that the stereotypical nerd is fat or neurodivergent or otherwise in some category beyond white dude, that's not what gets them bullied. (Also let's not forget that the nerd's archenemy who does the bullying is also usually a white man) It's their failure to perform hegemonic masculinity appropriately. George McFly vs Biff Tannen could be contrasted to Carlton Banks vs Will Smith. In a lot of the older pre-gamergate lore nerddom was broadly considered a kinder and more welcoming group, at least in part for this reason, and given how many fat, neurodivergent, nonwhite, nonmale, and nonstraight people identified as nerds over the years I don't think that was inaccurate.

Rather, I think two things happened that led to nerds going the way they did. Firstly they grew up and the problem of not performing masculinity correctly shifted from being on the football field to being in the boardroom and the bank account. A lot of computer and math nerds went to college and turned into tech and finance bros. Even those who didn't go into one of those fields started aging into the most profitable phase of their careers. You can see the fantasy of it become more common as the new millennium ticked along, with the narrative shifting from "showing the world we're right" to "buying their employer and forcing them to lick our boots clean". Along with this (arguably because of it), most of the rallying symbols of nerddom - comic books, anime, science fiction, fantasy, space, etc. - became the mainstream titans of culture. If the core of nerddom was a failure to appropriately participate in hegemonic masculinity and the resulting loss of social status, that loss of social status was no longer really happening. In many ways the rising diversity among nerds directly contributed to this since having women in the demographic meant it was no longer as toxic to your chances to ever get a date. Being a nerd no longer inherently meant rejecting that vision of masculinity.

But the fallout of these changes was a rift between those who rejected hegemonic masculinity and those who had merely been rejected by hegemonic masculinity. And this rift was easily exploited and magnified by fascists who linked the criticisms of nerdy past times from the former group to the latter's anxiety about losing their newfound social capital. You can find echoes of this in the discourse about "nice guys", particularly in the hand-wringing kind of reactions we saw from the Sneerable Scotts Aaronson and Siskind. And all those nonstraight nonwhite nonmales who were still on the outs with the broader culture of heteronormativity, white supremacy, and patriarchy found that they didn't actually need the "nerd" identity as strongly as the increasingly reactionary straight white dude contingent. And that basically abandoned it to the fascists.
