Some local politician is running ads bragging that he is a "true conservative". One of the ideas he advocates on his televised panderfest is that of making English the Official Language.
Wasn't it just a few years ago that Americans were laughing at the French government for passing all sorts of silly "cultural preservation laws"? I guess bad ideas are contagious. Now American politicians have decided that "The American Culture" is so weak and pitiful that it needs legal protections to survive. Unfortunately they have a lot of ill-informed support.
Any "culture" that can not survive being exposed to another probably does not have much chance of long-term survival anyway. If it has merit, there will be people who make a point of passing on the culture's unique attributes. To people who really care; not to people who are forced to submit.
