I've worked alongside a lot of black people, and I mean a lot. I've also lived in areas with a high black populations. What I've observed over the yeas is that there is a marked difference in diaspora blacks and African blacks. Working with many people from Africa I found them to be mostly very polite, often great fun to be around and that only one person I remember played the race card and he was a Nigerian. Another thing I remember, that was a bit of an eye opener, was that the women were much more attractive. Not because they were particularly great lookers to my Western eyes, but because they're far more natural, graceful and feminine than most of the diaspora I've met. It was quite a profound experience to realise, not only am I not on edge around these people, but they're likeable, quite different in many respects, but likeable nevertheless.
Conversely, I've had many bad experiences with 2nd, 3rd and 4th generation West Indians. I've not met many I want to be around for long. They're all too frequently hostile, hustling, posturing or obnoxiously loud. And you don't have to wait long before the chip appears on their shoulders. And they can't take any form of criticism from a white man. In this respect they're like damaged children. Being out of Africa for so long has not been kind to them. But, then, they've been subject to decades of propaganda and social engineering and firmly believe they're the most hard done by people in the history of mankind. This black holocaust mythology is hardwired now and only a concerted, deprogramming effort for at least 2 maybe 3 generations would be needed. Even then it would be better if they lived in the land of their ancestors, their true homeland, for them to find their dignity.
