There are and have been pockets in immigrant communities where e.g. older members would live their entire lives in US and never speak a word of English. But conversely, no one expected the rest of us to know Chinese, German, French, Italian, Japanese, Russian, ..., etc. But somehow now we are supposed to accept a sizeable subset of our nation to only speak Spanish.

I do not care if it is not a "good look" by some standard. What I care about is cultural and value system continuity and national cohesion.
