My native language is English - I am an American citizen - that is not impacted just because I speak other languages. Anymore than going to graduate school made me less American.
Only someone like you could be this dense.
Look, these people are not here to assimilate.
Those 20-30 million people that will be granted citizenship by this egregiously stupid bill are not interested in preserving any vestiges of American citizenship, and they could care less whether or not you speak Spanish.
That is a demand, a prerequisite, for surviving in this new society of ours, not a preference.
