Me? I don't mind. Typical knee-jerk reaction to anything threatening that which is seen as "sacred" (like burning the flag). It would seem to me that a real conservative would be trying to figure out how to profit from it rather than condemn it (I'd be the guy selling the flags at a tidy little profit).
I think the debate over language is a little weird, especially in the Washington DC area. I've been to the Walmart and heard French, English, Russian, Greek, Hindy, Arabic, and Spanish being spoken. The signs are only in English and Spanish.
I do think that they should learn English (to keep themselves from being isolated) just as I would learn Spanish if I were to work/live in a Hispanic majority country.
