Please enlighten me (and I'm sure Kevin has an answer!).
When you're in college seeking a degree that will lead you to a career in teaching, business, science, or when you already have a degree, what terrifies you about foreign languages? Why is it so alarming that sometimes, instructions and directions are also written in Spanish, causing you to cry out, "If you're in our country, speak our language"? What about your TV, your cell phone, your blender that came with instructions in French and German as well as English? Why are all Latinos "the Mexicans"? When you're not pursuing a career in landscaping or restaurant work, what is it that irks you about migrant workers? The taxes, you say. It's all about your tax dollars. If that's the case, then you ought to be outraged the majority of the time--park and school closings, squandered state budgets, government embezzlements.
What are you so afraid of?
