No one's trying to control what they speak at home. It's when they want to speak to those of us who don't feel we should have to learn Spanish, Italian, Chinese, Lebanese, Turkish, Urdu, Yucatec, Nahuatl, Serbo-Croation, Icelandic, French, Russian, Lithuanian, Greek, Ebo, Swahili, Portuguese, and Tagalog to accommodate the quivering, delicate sensibilities of all the immigrants who come to America. Just you wait till the day that some Spanish-speaking Mexican gets screwed over at the welfare office because the Chinese-speaking social worker doesn't speak Spanish, and said Mexican issues forth in a hissy fit, "Necessitas aprendre espanol!" (or whatever) and gets called a racist for it. I will be laughing somewhere, you can bet your sweet patooty.
My honey's first language is Tagalog, and the vast majority of Tagalog speaking people assimilate into American culture quite well.
