I can not understand this subject at all. The world really does not make any sense. Here we are again at the point of whom has the right to return. It makes no logical sense to me at all. Somewhere not far from here is the city of gold, Eldorado. I take my compass, a small volume of ST Augustine and a treatise on Alchemy and I look for it all the time. But it really does seem to have to do with my bank account more than anything else.
My experience is that it takes three generations to learn English and that the third generation usually is not bilingual. The first bilingual schools were German in the 1800s I don't remember that causing a problem. The rest I just see as hysteria and xenophobia.
