Its a welcome news indeed however, this is not the first. Saudi Arabian women are very important component in the society and are playing very critical role in many fields.This is a pretty big step in what many will call a right direction. Saudi Arabia is already pretty westernised and this is just another move in that direction. I think it's pretty good for the country and their relations with other western nations.
Saudi Shoura council (parliament) consist of both gender so this here isn't something new. The rest of your post is completely untrue. Google can help if you want to learn about Saudi Arabia. Its unwise to speak about something that you don't know of or experienced as it will make you look bad at the end.I had seen this thread but it's only now that I get to read it. At first I thought it might be something else but now it dawned on me that a woman councilor is a government official in a chauvinistic (pardon me for the word) country. I have friends who have worked in Saudi Arabia so I know that women are treated as second class citizens. They cannot walk side by side with their husband in public. Also, women are not allowed to talk to men in public. So is that woman councilor a paradigm shift in Saudi Arabia?
