I think that it's a bit of a stretch to say that the language they use means they're mocking people with disabilities or homophobia. Using words ironically just to be edgy is completely different from believing others to be inferior or an invasive entity to be defended against. That's very apparent when you talk to, say, an angsty teenager versus an actual ethnonationalist or even just your garden variety civic nationalist.
They might use the same words, but mean them in completely different ways, and actually be expressing very different things. I think that as it pertains to the internet, certain dialects of edgy, slang filled english are as close to a global lingua franca as can be considered possible. You can't paint all of these people with the same brush. Aside from speaking the same dialect of english, they use it to express very different thoughts, no less diverse or varied as those who speak other ones. This nuance will get missed if you overliteralize what they say and take it at face value.
Stop moving goal posts its a bad look.
I say this as someone who frequented both communities at one time or another: they are very very very alike. I wouldn't be surprised if this who thing is a charade to take money from 'normies' as much a wall street.
