Well I think the arguments were that Roxas was Ventus, given that Ven preceded Roxas. They were "right," at least to a very certain degree that I don't need to elaborate upon.
I think a more appropriate example would be Riku's and Vanitas' darkness suits and fighting stances.
No the arguments was that Ventus was Roxas, they would argue that Roxas was Ventus reborn.
The only part they would've been "right" in is design to a degree.
That is a better example Dx
