Close to the edge but not racist. PC gone mad again as you have said.
It has to be put in context. It is like saying Henry VIII was a mysoginist all because he beheaded a few of his wives or the Duke of Cumberland was a tad evil all because he took the eyes of many a scotch man. Hogwash.
One has to remember when these books were written many an African was an uncivilised person, and many are today. The Empire had little effect in these tribal colonies and today many still practice witchcraft, cannabilism and walk around without shoes. Spears and grunts were the norm for these tribal folk. The natives, as often called by colonialists, were a fearsom bunch who refused to accept anything "modern" or right. I am not saying they should have totally lost their way of life, but when they often shrink heads for fun and wear those tight braclets around their necks, we had to interveen. Also, I understand, female circumcision was and is still the norm in Nigeria and parts of London. And that is wrong-diddly-wrong.
It is wrong to assume all black people look like monkeys, but considerring we ALL descend from apes and black people are darker skinned than whites of course they look like monkeys. If there was an albino monkey, which I am sure exist, then it will look like a white man. And people like Pete Sampras, Will Young and Mark Walhberg, who are all white, still look like monkeys.
The 1940's was too preoccupied with war and Hitler to worry about minor aestethics.
