If they don’t want to speak English, then they sshould go back to the Phillippines.
Philippine children as a general rule are required to learn to speak English in the Philippines. In fact, you are much more likely to run into an English speaker in Manila than in Los Angeles, New York, or even Kansas City.
They are pissed because they are being treated differently, not because they cannot speak English.
I think that's the sticking point. I'm all for English-only, but it has to be blanket, no discrimination against a specific grouop.
