I think it’s just really important to me that Homestuck doesn’t have a straight man.
There’s no one in Homestuck whose role is to snark about how wacky everyone else is, to be the reader-insert character aloof from the shenanigans around them. And every time anyone tries to take on that role, it’s shown to be a self-destructive facade. Rose, Dave, Karkat, Equius, Eridan, Jane, Dirk… all of them attempt to be the “serious one”, but their character growth comes when they begin to move past their instinct to make fun of their friends (and, ultimately, themselves) for emotionally engaging with the world around them.
Homestuck has always been a comic about laughing with its characters, not at them. Where the conventionally unusual is celebrated, not derided. And that’s a worldview that is worth celebrating and defending.
