See in FFX/FFX-2

They make Guado become bad
They kill Ronso not human
They despise Al Bhed (though Al Bhed is human)
They treated Hypello as servant
They make Shoopuf a taxi, the elephant must be tired
They make Kimahri less useful like the other in battle

In FFIX, they specially respect non-human, Steiner and Beatrix is the only human playable character.

FFVIII specialize in human, not too much race of unhuman in FFVIII.

FFVII Nanaki is treated well, in AC, Nanaki is treated like a dog, Nanaki...is my favourite.....
Cait Sith also, He just like Kimahri, less useful, can they make this unhuman useful a bit.

Square have chosen, wedo not have the right to do anything, that's their choice.
