according to this WILD subreddit, "Race-mixing" is a negative thing because it encourages the opposite of what nature intended. one guy said "A White man (average IQ 100) breeding with a sub-saharan African woman (average IQ 70) will lead to a child with an average IQ of 85. Nature intended for us to strive towards being the best, the smartest, the fastest, the strongest, and not mediocre, and not to regress to a lower ability. Hence, only the good genes should be spread, and bad genes should be eradicated." But What exactly constitutes good and bad genes? It's clearly a topic for another discussion, but in general, this is the direction white supremecists want us to move towards, and in their opinion that disabled children should be either killed or dead because they are a burden - wtf?!
