Cambridge isn't exactly representative, either of americans' attitudes towards immigration nor of the immigrants themselves.
Then immediately someone responds that where we live is not representative of America. Though let me remind you, if you believe the "real" America is the people in Alabama or the bureaucrats creating asinine policies that keep out brilliant foreign students, think about how much worse things would be without those of us in places like Cambridge to actually speak up and vote for candidates like Elizabeth Warren and say we don't like the way the other side is trying to run the country.
You don't get to say that "your America" does not include the rest of the country, not unless you're willing to take up arms and defend Boston as a sovereign entity against foreign invasion.
