I wanna say we've done this song and dance over and over and outside of GUNS you've never really been able to identify an american culture that isn't founded in something foreign.
The idea that a government has to force a culture on anyone is silly. A government governs, the people create and evolve the culture. The more and more people scratch and pick at the differences the more and more people start to notice them and make them a big deal. The coke commercial is a perfect example. It's not really a big deal, it doesn't change anything in America, but now there's a highlighted sentiment that not speaking english is unamerican when it's not.
We dont' have a common language and we don't have a common culture. Never have.
