A cross of unlike species induces a degree of sterility. What of injuries to offspring in general? A Black mixed with a White has a higher likelihood of inviability, from low birth weight to congenital malformity. An Asian with a White makes frequently a mentally ill child with awful health that threatens the mother's wellbeing. Mixed race persons tend to be practically predestined to fail. Latinx, queer abroad and at home, perfectly illustrate this issue. Disorder, deviance, and misfortunes all spell 'sterile' down the line.

Seemingly close mixture has its consequences too. Since the Northwest European surpasses the South and East Euro in every good respect, a crossing with SE or EE can be a step down, an injury, for the Northerner. General intelligence drops, overall cognitive function worsens. The White race would grow physically weaker given the Northerner's significant strength advantage over the South and East, the South being shorter, and the East hosting the largest share of chronic illnesses.
