>Unlike the author I know what I am talking about because I am an actuall Mexican.

That means you don't know what you're talking about. If you are immersed in it you definitely won't be confused about it at all. This article is written for people who are not Mexican observing from the outside.

It's like someone from the US claiming the imperial measurement system isn't confusing. The more immersed you are, the less relevant your view is to outsiders.
