Can anyone explain why, at least, the bios for Raph & Don (1) contain incorrect info and are (2) locked against corrections?
It has never been confirmed (in any iteration where Raph & Don are the middle sons) whether Raph or Don is older. But, for some reason, the creator of their wikis here states that Raph is older like it's a fact?? On top of that, their pages are locked against anyone editing it to say that actually it's never been stated who's older.
People can headcanon whatever they like based on their personalities and interactions, but the fact of the matter (as should be represented by a wiki) is that it's never been confirmed one way or the other.
