A powerful video. The more the economies of EU go into the tank, the greater the rise of nationalism and the defense of culture and language. It will have electoral consequences given the very high unemployment rates among the young.
There is a similar dynamic beginning to work here. More slowly at present because things aren’t as bad just yet.
That's the problem. The trouble with a mere defense of "culture and language" (and identity) is that every country and people on earth has a separate one. If not careful, such an attitude can veer into henotheism: the idea that there is a separate "gxd" and separate "truth" for each nation.
What we need isn't language, identity, and culture, but the Laws of A-mighty G-d.
