damn I rememeber in the 70's and 80's ... we laughed at people's expense all the time it was the norm. I feel ashamed of that.
to answer your question it's because they were hunters and gatherers for centuries in africa and when brought to N. America they were bred like race horses.
I agree with him on this one. There are segments within the African American community which were bred to achieve larger and more dextorous slaves. As a result, there are many African Americans who are very skilled in numerous physical competitions. Why else would blacks make up 50% of the draft and only 10% of the population. Africans aren't larger then Europeans. It has to deal with eugenocis. It's not a comfortable topic because it deals with our racist heritage, but it's true.
Read lodui's post. Slaves were bred like work horses. A persons genes are something that are known to be passed along. Therefore proper forced breeding, more often than not, will produce desired effects. Especially when you have a large population to work with. The more attempts made, the better the chances at success. If you make two people with desired physical qualities breed enough times, you will produce a child that has a combination of the desired genes eventually. The law of statistics backs it up. Ps. I've never seen either movie.
I dont want to insult any black girl / guy reading this, but I think that there is also such a thing as black racism, or perhaps not racism but prejudices abgainst white people. This is based on my personal experience both in real life and here in the forum. I have sent messages to black girls here and also tried to flirt with them during threads, but they have either ignored or even insulted me. I think their behaviour towards other people in this forum is different because they think there is some chance that those might be a "black brother" but in my case they seem to think this is highly unlikely since I identified myself as a German.
