re: Is English still the primary language in US?

Exactly correct. I remember a couple of decades back, and when I'd be at a grocery store or whatnot, and overhear voices speaking in a 'foreign' language, it would immediately catch my attention, as it was such a rarity.

Same exact town, and these days, I'll go into a store and very often hear roughly 60% of the voices spoken in a foreign tongue.

It really no longer feels like I'm in America anymore. More like some third-world enterprise zone. Really no sense of connection to a shared culture and society anymore. Patriotism has become pointless, as it just doesn't seem like a real country anymore. Just a sort of grubby, international bus-stop with disparate characters wandering around.
