So the argument seems to be: even serious oppression of women is not as bad as dropping bombs on them, therefore the varieties of female oppression are merely simple cultural differences, carry no weight of ethical value, cannot be compared as right or wrong, good or bad, even better or worse.
Based on my personal experience, I would say that women wearing veils in Islam [which is probably about 5-10% of Muslim women overall] are as as oppressed as women wearing any other piece of clothing rather than going naked. By your criteria the only free women would be those in Girls Gone Wild or other porn actresses.
How many women want to be them?
