I went through a phase that it bothered me. Then I realized low IQ people are only a problem when they are weaponized for some reason. Under the right conditions 'low' IQ people are just another segment of a cohesive society. If we got rid of all the low IQ races we'd still have low IQ whites. If we went further and got rid of all the low IQ whites we'd still have 'lower' IQ whites. Having a range of IQ's is just part of civilization. It's a stabilizing element.

In fact I'm not really a huge fan of IQ analysis. It's useful to help explain why racial mixing is bad but there are so many reasons why non whites should not live with whites. There are so many more dimensions to what makes someone implicitly near kin and another person an outsider. Aggression, temperament, sense of fair play, grit, playfulness, inventiveness, compassion, religiosity, inquisitiveness (even aesthetics, odor, sounds, tone, etc). These are all traits outside the scope of 'IQ'.

If you get over focused on IQ you run the risk of keeping too many non whites around. You might even think it's a good idea to import non whites. People that over the long run would destroy the uniqueness of whites. High IQ immigration is just as dangerous as low IQ immigration. You start running into the law of diminishing returns with higher and higher intelligence. Many high IQ types cause harm to themselves and others.

I don't like whites because they have a high IQ. I like whites because they are whites.
