Racism
I disagree with how little was said when race was brought up. Mainly, they tested black people and found simple statistics. I didn't think that the statistics were very significant. They should have gone further.
One big mistake people make when interested in racism is just pointing out blacks, when other races are the ones with more similar things to contribute civilization-style-wise. A "ditzy" girl on TV around 2003/2004 once said and so have others insisted/emphasized and imprinted that there are merely 3 races, black, white, and Asian. It's funny how people who aren't Italian/Latino have more trouble with the Italians/Latinos than the Italians and Latinos with one another. People are bad, for whatever excuse or reason, therefore, and it's a much more interesting topic to me than whatever else they talk about.
The book swiftly brushed over racial discrimination, that blacks have to live in the US and feel uncomfortable heritage-wise. There is a picture in the chapter of some plants with nourishment and some without. People get so fixated on black people feeling different, but they don't do anything big about it socially. You might get Martin Luther King day, but that's a farce, not much talked about the Asians, neither.
The book didn't notice that people actually believe in not letting other races "make it" because they are ahead. That is certainly not a very Christian thing to do. In 1 John 2:11, it says, "But anyone who hates a brother or sister is in the darkness and walks around in the darkness. They do not know where they are going, because the darkness has blinded them." I've always believed this strongly. I don't believe people are really fair to other races because bad people are encouraged by countries like England.
I think the book is racist because it doesn't touch on these issues really, just sorta mentions them.
