omegaverse yuri & twincest

am i the only one bothered by the fact that two of the very few omegaverse yuris that exist are sayohina djs? (sayohina are twins btw) i could go on and on for days saying why i hate incest. i have 6 siblings and could never see any of them as a romantic or sexual partner. so why is fictional incest so popular? do people want to fuck their kin? maybe it’s like people saying, “well it’s fictional” but fiction has always affected reality. even if it didn’t, how do you justify identical twincest? what is hot about seeing two people who look exactly the same fuck?
