Rapunzel is a young girl with blonde hair, and even Alexandra Metz is a pretty girl, she destroys her icon, just like a white girl would destroy Tiana's icon.So theories use to merge the two stoies because Alexandra's part would work if Rapunzel is Tiana. They wouldn't cast a black girl for Rapunzel's role. Plus the fact, that the writers said  that they were thinking to add Rapunzel and Tiana into the storyline.
