There is a natural disgust in the minds of nearly all white people to the idea of indiscriminate amalgamation of the white and black races. . . A separation of the races is the only perfect preventive of amalgamation, but as an immediate separation is impossible, the next best thing is to keep them apart where they are not already together. If white and black people never get together in Kansas, they will never mix blood in Kansas.
Here's an easy one: "Race is an entirely social construct. " No, it's partially one, depending on how any given society seeks to define it and its implications. But there are basic things such as skin color and hair texture. Even a Martian who'd had no exposure to human "social constructs" would be able to spot those differences. But no Martian, as hard as he tried, could point at a "culture" or to "equality. " Those are the social constructs. Those can't be measured in the same way as human DNA.
Thee might observe incidentally that if the state paid for child-bearing it might and ought to require a medical certificate that the parents were such as to give a reasonable result of a healthy child -- this would afford a very good inducement to some sort of care for the race, and gradually as public opinion became educated by the law, it might react on the law and make that more stringent, until one got to some state of things in which there would be a little genuine care for the race, instead of the present haphazard higgledy-piggledy ways.
Since I do not forsee that atomic energy is to be a great boon for a long time, I have to say that for the present it is a menace. Perhaps it is well that it should be. It may intimidate the human race into bringing order into its international affairs, which, without the presence of fear, it would not do.
Now, I've lived long enough to know that race relations are better than they were 10 or 20 or 30 years ago no matter what some folks say. You can see it not just in statistics, you see it in the attitudes of young Americans across the political spectrum. But we're not where we need to be. And all of us have more work to do.
In no organized sport do the participants have to endure days of struggle just to get to the starting line of their event. The option to drop out of a race that is going badly does not exist for a climber halfway up a big route, and may entail more risk than pushing on. A team of volunteers will not be waiting with warm blankets and hot food at the next bivy ledge. When you reach the summit, having overcome the challenges that inspired you for months or years, you are not at the finish line. The race is not over. You can't relax and let your guard down like a normal athlete.
