No. And when you find yourself calling people unamerican, you're doing horribly. Historical example? McCarthyism.
Does the ACLU stand for American as in persons, American as in culture, American as in country...? Unless you work there, not up to you.
ACLU getting in on this implies America as a lot of things. America as a dream. America as a land of laws. America as a corporate entity honoring agreements. And more.
Your attitude is the #1 difference I see between "democrats" and "republicans": Is America an exclusive club, or an inclusive one?
