If you think that's bad, lesbiancore technically exists on this website but is called Sapphic-core. It's a cottagecore, greek renaissance wannabe in my own taste. (Check All pages if you don't believe me if they haven't deleted it yet.)
But I did discover this page on this wiki abput this "sapphic-core" that seems VERY unprofessional (I don't really write pages because I'm afraid I'll screw up but this seemed less like a report you'de need to write in an exam and more of something you'de find in some fanfic.)
Off topic: the use of "amn't" is simultaneously the most aggravating and endearing thing ever, props to you.
On topic: the page is not only unprofessional, but completely redundant. It's trying to play off the "cottagecore lesbian" thing, which is completely unnecessary. Not as offensive as lesbiancore, but wrong all the same.
