I think the problem with White Privilege, Male Privilege, etc is it is incredibly subjective. It differs depending upon where you live. For example I know there are places that have White Privilege, yet it doesn't apply where I have ever lived. I've seen people not get jobs due to being white and a position needing to be given to a minority. As far as Male Privilege that also depends a great deal upon if you are affiliated with religion. All of the religions based on Judaism (Jewish, Christian, Islam, Mormon, Jehovah's Witness, etc) are heavily patriarchal. Thus there is definitely heavy Male Privilege if that is your faith. The again it is still subjective as there are likely denominations of all of those faiths where that issue has been impacted.
In fact, religion has a lot to do with male/female privilege. There are some denominations of Wiccan for example that are very heavy on the female privilege side of things.
You are correct! In the modern West, patriarchy and male-privilege only exist in religious cultures. To the secular culture, privilege has been more or less neutralized -- or at least it approaches that. Fantastic post :D
