This comment is simply false. We can have a robust sharing of ideas and cultures all within the context of a single language.

In speaking a common language we gain tremendously both in unity and the opportunity for increased cultural sharing. Imagine a family in which everyone speaks different languages. There would be little interaction; the family would fall apart. Nations have historically fractured in this way along linguistic boundaries, and by not encouraging a single language in a country, we invite division, balkanization and national fracturing.

I'm curious as to why you are against a single language dominating in a country. Are you uncomfortable with people being expected to make the effort to learn a new language? Or do you just not care about nations (or the USA in particular) as units and don't mind if they fall apart.

Imagine if different areas of the United States still spoke the languages of first-generation immigrants.

You'd have the French, German, Dutch, English, native tribes, Spanish...

Not the United States of America, but the United States of Austria were actually a serious proposal: https://en.wikipedia.org/wiki/United_States_of_Greater_Austr...

The issue usually isn't ethnic tensions, it's usually disenfranchisement expressing itself through nationalism.
