There's so many truthers, like Tyler Hansen, convincing their followers that cloning doesn't exist and everyone is a fallen angel or shapeshifter.
Celebrities look way too much alike and appear to be made in a petri dish/test tube. They are destined to be famous, placed with parents who have signed over their children's souls. Many aren't just "discovered", they are groomed and will promote whatever narrative their handler tells them to. If they stray from the script, they are ruined, blacklisted, suicided or killed. So many movies/TV shows have told us about cloning, even The Flintstones had clones of Freemason Fred.
