Women are only oppressed if they feel oppressed. That might sound strange, but it is true of anyone. The fact that many Muslim women choose to wear a hijab or whatever form of headwear is a personal and religious choice. It is only oppression if they wish to remove it but are beaten or threatened if they do so. I'm sure there are Muslim women somewhere who feel oppressed by the garments their religion dictates, but I'm sure there the majority do not feel oppressed...I would imagine most of them even feel "special" that they do so.
