Short answer: No.
my understanding from a semi biblical lense is that it's not ideal. However with that said, races are more granules than many want to admit. I am of Colonial Americana stock. I am different from my crush who is slavic blooded. We are different races. We have greatly differing phenotypes, and I will simply assert greatly differing temperaments, ways of interacting with the world, perceiving, reacting to stimuli and stress, and it all goes on. We are both broadly "white", but vastly different races.
Would it be bad to mix my blood with her? No. Especially if we are trying to live Godly lives with one the other.
Would it be bad if I mixed my blood with the Brazilian friend I had? She's a Coblaca, mostly native with some Portuguese. I will say no, for the same reason I gave for my white crush. Will there be potential struggles for the boys of that marriage? Only if society puts in it the child's head there's something wrong, as I would hope to raise the boy as my own child and not an alien.
Are there biological realities to these things? These mixings? Yes. I'm not going to deny that. However I'm not going to be a retard calling just short or explicitly for the killing of mixed children.
And further, I don't believe there is anything to call a "master race". So I don't buy into the pseudo eugenics argumentsRT:
