The Spaniards, who were hot-blooded and didn't think too far ahead, mixed with the Indian women, raped them, forced them to practice their religion, and thought that meant they were turning the country white. Those Spaniards believed in a mongrel whiteness. But they overestimated their semen and that was their mistake. You just can't rape that many people. It's mathematically impossible. It's too hard on the body. You get tired. Plus, they were raping from the bottom up, when what would've made more sense would be raping from the top down. They might have gotten some results if they'd been capable of raping their own mongrel children and then their mongrel grandchildren and even their bastard great-grandchildren. But who's going to go out raping people when you're seventy and can hardly stand on your own two feet? You can see the results all around you. The semen of those Spaniards, who though they were titans, just got lost in the amorphous mass of thousands of Indians.
