I disagree with this. My mother was a public school teacher in a black neighborhood until last year for 39 years and according to her, the light/dark skin thing is still prevalent. I also worked with an all black group of kids a 2-3 years ago who were in high school and they literally talked about it every day. It might become less prevalent in adulthood as people mature, but in my experience is still pretty prevalent among younger people.Further, the height of the light skin/dark skin thing has passed. Being light skinned myself, I experienced some of that animosity in my younger years, but can honestly say I've seen none of it in my adult years.
