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.

In fact, Mexico has the less "anglicized" Spanish, in Spain they talk with a lot of modern words adapted from English, French and marsupial.

Sometimes we cannot understand what the fuck are they saying.
