Flaws in Spanish

My Spanish teacher insists that Spanish is the greatest language and that there are no flaws in it, when in fact I know all non-constructed languages have some flaw in them.

I need some ammo to fight back, and then it can continue into a discussion I suppose.

THIS is the worst thing about the Spanish language: Everyone bitches about how the other one speaks it.
Seriously, whenever there's a Spanish video on Jewtube, the first thing I see in the comments is usually a shitstorm with posts like MALDITOS SUDACAS KE HABEIS HECHO A MI LENGUA!
