~Former Congressman Abraham Lincoln, Fourth Debate with Stephen A. Douglas at Charleston, Illinois, September 18, 1858
“And inasmuch as they cannot so live, while they do remain together there must be the position of superior and inferior, and I as much as any other man am in favor of having the superior position assigned to the white race.”
And that is an example of one type of attitude that will result (and has resulted) in the conflict between the two races. If you were black, regardless your IQ, how would you react to a bunch of whites making that assertion and worse forcing it on you?
That is why I say that they cannot peacefully coexist for long.
The other side of the coin also presents a problem. If one group of people is indeed, on the average, less capable and the powers that be dictate that you must treat them as though they’re equally capable, you would also become belligerent at someone forcing you to not believe what your eyes see, which is basically the situation today.
