Not speaking Spanish as a sign of being an anti-illegal immigrants may be a good thing.

But not speaking Spanish at all is a sign of rejecting a lot of very beautiful and useful knowledge.

If you write: "In a certain village in la Mancha which I shall not name, there live'd one of those old fashione'd men of lance upon a rack and greyhound..." you definately screw and destroy this text —one of the greatest in Literature. [img]graemlins/no.gif[/img]

----------

Os Deuses da tormenta e os gigantes da terra
Suspendem de repente o ódio da sua guerra
E pasmam. Pelo vale onde se ascende aos céus
Surge um silêncio, e vai, da névoa ondeando os véus,

Primeiro um movimento e depois um assombro.
Ladeiam-no, ao durar, os medos, ombro a ombro,
E ao longe o rastro ruge em nuvens e clarões.
Em baixo, onde a terra é, o pastor gela, e a flauta

Cai-lhe, e em êxtase vê, à luz de mil trovôes,
O céu abrir o abismo à alma do Argonauta.

Fernando Pessoa - "Ascencion of Vasco da Gama"
