well finally u agree that discrimination still happens against women in the west as well... likewise it happens in east, we why would middle east be considered an exception and not allowed or be criticized of such discrimination.

i must say i cannot challenge all of the examples you have listed but:

women not being allowed out of the house without a male chaperone - Dont you think this is a very good initiative to prevent any sort of harm that may befall a woman that she cannot handle and would be better off with a male support... (now dont argue that women are equal to men in all aspects... it may be true for only a few women not the majority)

not being allowed to drive at all in Saudi - though thats only in Saudi... we are all way aware of lady drivers and the chaos they bring to road... youtube is filled with samples to prove it :D

women not allowed to watch sporting even in Iran is really new to me infact i have heard of Iranian women's football team that was unjustly disqualified from olympics because they choose to adhere to their culture... wtf.

however, my opinion in this matter will not be of much weight as i am a man and cant voice the actual feelings of a woman, rather can only express the possible motive of a man who would apply certain very few strict rules on a woman
