It's true. In traditional Muslim society, women are not afforded the same freedoms as found in most western societies. It's part of their culture.
In my opinion, this is the single largest TRUE reason that we have so many peoples in the Middle-East that are anti-American. America, in many ways, represents the Muslim idea of western society (thanks to the TV, mostly). They see America as a threat to their way of life. Knowing that openly challenging America on this would make them appear backwards in the eyes of the rest of the world, they choose other "reasons" (ie, excuses) to push otherwise peaceful fellow Muslims into terrorist activities. Traditional Muslims find the freedoms of American (and other western) women offensive, and will do almost anything rather than change their ways of thinking. As I have said before, religious differences are not the cause...just the excuse.
