I think this post is talking about two types of fans and treating them as one. There's the ironic homestuck enjoyers, and theres the nostalgic homestuck enjoyers, and i don't think they're exactly the same. The nostalgia!enjoyers don't necessarily enjoy homestuck ironically, a bunch of my favourite fanworks are written by people who either dislike what happened after cascade, or what happened after game over. And those fanworks are written most sincerely and both continued to be written after homestuck ended, because they did genuinely like the earlier parts of homestuck. Usually, they really like the characters and just ignore everything that happens after the point where The Story stopped being quote unquote Nice to them. Which makes them particularly annoying if you're talking character or story analysis, but it doesnt make their enjoyment ironic.

I have still hope that the ironic!enjoyers will turn around after a few years. It happened to twilight too, it used to have this huge antifandom, but during the lockdown people suddenly started enjoying it sincerely again (back when the "effervescent" meme became huge). I get why you'd be an antifan, the fandom used to be extremely loud & annoying (a lot of conventions have gotten a lot more strict about their rules bc baby homestucks Did Not Know How To Behave) and it has a lot of things that you can pull out of context to point and laugh at (or possibly point and yell problematic at if that's more to your taste). Thinking your old interests are Bad And Cringe is part of growing up, and I really hope the antifans read the entire comic + epilogues + hs2 + beyond canon again and realise that all of it is a lot better and more cohesive than they remember (and that psycholonials isnt personally out to Get You)
