It's not the Anthem.

Last time I looked, the National Anthem wasn't filled with socialist tripe such as this:

Sus estrellas, sus franjas, la libertad, somos iguales

Somos hermanos, es nuestro himno.

which translates to

Its stars, its stripes, the liberty, we are equals

We are brothers, is our hymn.

If someone's anthem needs to be rewritten, it is the Mexicans'. Here's part of it:

Si a la lid contra hueste enemiga,
nos convoca la trompa guerrera,
de Iturbide la sacra bandera,
mexicanos, valientes seguid.

translated into English:

If to the struggle against a hostile host
The warrior trumpet calls us,
The sacred banner of Iturbide,
O Mexicans, follow valiantly.

If WE're the host, buddy, doesn't that make YOU the parasite?

Damn straight I'm hostile to parasites. Especially those who break laws to enter the host.

And our warrior trumpet's bigger than yours, so don't get any ideas.
