You'd be surprised. Maybe she had parents who grew up under the British colonial system and experienced the stratification that it brings along with it. I don't get it though. My mom grew up under the same system, yet I have one aunt who got into this stuff when she came to America (and attended the very same BROOKLYN COLLEGE).

You know, I worked 2 UN missions during my military time and I got a chance to meet several real Africans. Interesting things: 1. they were all educated in proper oxford english and 2. they all said the same thing: their countries were better off under colonialism then now.
