“Multicultural” societies have, and will probably continue to have, an extreme-violence potential inherently built into them. Such societies need very long periods, usually centuries , before racial, ethnic, and cultural differences may become essentially irrelevant and violence decreases. A lot depends upon whether multiculturalism is celebrated in a constructive or destructive way within a society. Unfortunately, the latter seems to be gaining ascendancy in the United States in particular. Little Switzerland, with its seven-hundred-year-old confederation, is a place where the right mix was achieved, and even there it involved many growing pains along the way.
