What does becoming American even mean? This country is such a mishmash of religion, politics, food, culture, etc. As an average white guy, I'm happy if you just speak English and maybe put up something at Christmas.
I mean, I live in Eastern Europe and I'm currently watching an American TV series on Netflix while I'm writing this comment on my Apple MacBook with a podcast waiting for a listen later and there's a Sam Harris book on my bed. It's nothing like my heritage of what it means to be Hungarian, living in Transylvania. And yet you're sharing a lot of American identity with me.
It's just a thought I've been playing around with, but maybe that's why Americans have such a hard time finding their identity as Americans?
