What is wrong with thigh gaps tbh?

Why are thigh gaps seen as such a bad thing? Someone posts something about it and instantly everyone is saying no that it’s bad and what not. I’m trying to understand why? I want a thigh gap because I have very fat thighs that have never been separated in their entire existence. I’m so tired of burning chub rub and the amounts of pants I have ruined. I can’t wear skirts or shorts without ending up with a red inflamed patch of skin with broken blood vessels. The idea of my thighs not touching is heavenly to me, to not deal with this anymore. Don’t get why it’s such a bad thing.
