For me it would be the prequel doctrine on attachment I disagree with. Because Jedi had families and children in Star Wars lore before the prequels. Just like how the chosen one thing was made up and so was midichlorians.
To get the Jedi celibacy thing you have to go all the way back to discarded script drafts for the original film, the son of the suns prophecy for the chosen one thing. Midichlorians came from nowhere.
