Any threat to that status quo can not be tolerated.
If you look at it realistically, only one half of the white race ever really produced anything of value, the other side was just responsible for producing more of the first half. But that's not an ability which is unique to white woman, an Asian woman can give birth all the same.
A white guy who has no children at all is a much bigger loss than a white guy who has half-Asian children. At least he can still raise those to be proper human beings.
