I feel like reactionary nature of the Gamer identity has more to do that it was originally made up of white middle class nerdy dudes, a group by it’s nature drawn to the right.

Plus a heavy dose of capitalist alienation. If those gamers weren't being failed by our system so hard they would probably be your typical neoliberal techbro dipshits. Its that white middle class ingrained idea that they deserve better because they are part of the in group, but then getting their legs cut out from under them by the material realities of our system, and then the resulting social fallout that keeps them insular and unable to pursue relationships, reinforcing the alienation and creating a death spiral to reactionary gamer scum.
