Halo 2 is pretty explicitly about how this is not the takeaway to take from the Halo storyline. Even me at 15 understood that, and I was a moron at 15.
Unfortunately for millennial leftists who grew up with Halo, it’s one of the few media properties that the Right correctly reads as reactionary and belonging to them politically. It is, regrettably, kind of about this. It’s chudslop. Always has been.
