I think it is fair to say everyone likes human beauty. Whether or not we can agree on what beauty means, we do all desire it. Beauty may have its evolutionary value. We feel that beautiful people are healthy, intelligent and generally good mates for reproduction. Our ability to spot human beauty seems to help us select the right individuals for our continued racial evolution.However, racial purity is racial survival whilst human beauty is merely an asset to it. I do acknowledge that beauty has its place, but the importance of beauty is not equal in rank to that of racial purity.
In a world of individualist values people may be confused about the importance of beauty relative to purity or they may not want to take a realistic stance for purely ideological reasons. Racial survival does not depend on human beauty and there is a real human interest in racial survival. At best, human beauty may be an indicator of desirable traits for the race moving forward but it is definitely not the end all and be all of human racial interests. Whereas racial purity means racial survival, human beauty is merely an aid to racial survival. Therefore, beauty is not as important as racial purity.
