LOL, says the guy who writes multiple paragraph posts about the "white man" and the "black man" EVERY SINGLE DAY..... 
Every time a racial type topic is made I am almost assured "Parker" and G Thang" are on there bitching about something.
Poly, read the last paragraph, and your own, if their is a racial topic, who starts it? And what do people say in it? Gee, wonder why I'm in it?
Archer77, if you understand the history of "passing", maybe you might understand what that nurse was saying and others. Becaus a lot of times, black people, especially black women will marry white men to have lighter kids, hoping the kids can pass. I not saying that is the case with your brother and his wife, because I don't know them. Or you have issues later on where the kid doesn't know Jack about who he is, and black folk will tell him. You may not think he looks black, but black folk know oher black folk. There are things Jewish people will tell their own, Chinese, etc. And black people are noo different. There are some things you won't understand, nor your brother. Like black hair care and the like.
But, you also have a thing where, kids will act the opposite of what you want them not to be, a mixed light skinned kid may associate more with the "thug culture", because moms and pops want a proper son, not a "black" son. Get it? I have many many kids in my family on both sides, all of them were raise with the notion that they are black, no matter how light or how "pretty" their hair is.
You know what happens to the kids who don't get raised that way? They think that they are better than because they are lighter, until one day they have a epiphany, and somebody breaks that shit down to them, like on a GetBig board and calls them a racial slur.
Dr. Chimps, I've actually seen dolls that portray the Indian caste system.
