He is not advising Us to mix with the Animal-Man. Clearly! Because We do not believe in having any children whatsoever after 1945.

What he is saying is that when a few of the Hyperboreans (the "Angels") "fell for the daughters of men", it caused the blood of the Hyperboreans to become less pure and thus, entropy set in. We believe that the reason they did that was because they were horrified and disgusted with the way the Demiurge had set up his animal-men in endless life and death, with no way to escape, with no way to attain a Soul. In other words, some Hyperboreans made a sacrifice. It depends on how one looks at it.
