Zeus, are you saying that the quote that I came across (I wasn't actually looking for one, but just stumbled across it) does not appear in the Koran?
When you say "middle eastern cultures" are you including others besides Muslim? I have seen many notations that Muslims are migrating more and more into many parts of Europe, increasing their percentages of population in many traditionally non-Muslim countries.In large part, you are seeing middle eastern cultures trying to hang on by their finger nails against the onslaught of western culture. Cultures under threat circle the wagons and get very conservative. Pushed further, some will respond with violence
Evidently the problems there are similar to some of our US immigration issues, i.e. the newcomers are reluctant to assimilate into their adopted countries. The article I read about the head-covering for women law in France does not include scarves, but does include the coverings that conceal the face. I can see the practicality of that in a country that might require photo ID for legal purposes (like the photo required on my state's driver's license). The discussion on the law was whether it violated freedom of religion.
If I migrated to another country for permanent residence, I would expect that I should do so with the intention of adapting to a new culture to a large degree.
I admit that I do not know any Muslims personally. Nor do I know any Buddhists or Shintoists. I only know Christians, Jews, atheists and agnostics. I just try to keep an open mind about it.
