Your rational basis for opting out of learning English or math is what, exactly?
It is exactly the same as your "rational basis" for opting out of any other language: I don't see any (except, possibly, xenophobia, in your case).
I guess that Spanish is arguably a more relevant language to learn than Arabic, since it's more widely spoken in the US doesn't count. Or that I don't expect to go to a liberal arts college, so I'd be better off taking an occupational education class instead of any language doesn't count.
My supposed xenophobia is obviously the answer. Because wanting more choice isn't politically correct, and anyone who opposes the education bureaucrats one-size-fits-all agenda is a racist.
Come on Cynic. Would you or the vast majority of parents who railed against this have been remotely as upset if the language chosen for mandatory instruction was, say, German? Or French?
