I mean it is already sad to have your child turn out to be dumb, especially if it's unlucky variation to the negative. If you breed with a nigger, this isn't some chance that went badly, it's expected that the offspring is dumb.
Also there is regression to the means. If it were possible to breed smarter and smarter humans, there would have been people who would have done it. However that likely leads to incest and negative variance may pull heavier on outliers towards the average.
If your IQ is 110 and you think you can reproduce with a IQ 90 nigger, that thing is already above average for its race. Let's say due to variance it becomes a the average that is average for both races (70, 100), which is 85. Congratulations, with a little bad luck you have a retarded nigger-mongrel, instead of a midwit you can be "proud of."
