I'm not sure I quite agree with wojaks being inherently reactionary, but I do think that there's a ton of ableism that's baked into quite a few popular memes that came from reactionary spaces. Like there's an interest policing angle to some of the stuff about how it's bad supposedly that someone's intensely into a particular bit of media, the manchild archetype is very much built on autistic stereotypes and mocks them essentially for being autsitic, etc. Shit like Redditor is usually more clear that people are mocking people for being massive libs or chuds with beliefs they don't really expect real pushback on, but even that can sometimes be used to interest police over someone that uses it to talk about a special interest.

But the broader criticisms of superhero movies, video games, etc aren't really directed at any marginalized group, those are things that are mainstream as fuck. Everyone plays video games and watches superhero movies, often on Netflix. Jokes at the expense of consumerism are going to be p standard leftist humor.
