Yeah and there are people that speak Basque in Spain. However, you won't find many that are not Basque speaking that language. The Basque speakers all mostly speak Spanish.

Same thing in the US. Sure there are people that speak 300 languages, but the majority speak English. They are also spread out.

Only major exception would be Spanish

True, but that's out of a nation of 350 million people.

I mean, I understand the spirit, but that's bit too close to ethnic cleansing.
