Hate to disagree with you Desert Marine because we Jarheads should stick together, But this IS NOT, and was NEVER INTENDED to be a "diverse" country It was founded by English subjects for Americans, as an English speaking country, and for the first 190 + years all public business was conducted in English, I understand what you mean about first generation immigrants having difficulty with language and customs, thats to be expected, I'd have a rough time learning a new language as well, but of the European immigrants the SECOND generation always assimilated, Look at Russian Jews like Meyer Lansky.
But my main argument is that the root of "diverse" is "divide", and we all know what lincoln said about that.
