I think you're missing one of the main points of the wiki: this wiki is supposed to document aesthetics. (From the homepage: "Our wiki is a comprehensive encyclopedia of online and offline aesthetics!" (emphasis mine)). Kidcore, Traumacore, Babycore, Cripplepunk, (etc.) are all aesthetics that exist in some form or other.
(Side-note: Read the page on Cripplepunk. I fail to see why embracing disabilities and accessibility is (in your words) "absolutely detestable.")
