Racial purity is a difficult state to prove for many these days, but it does exist, though rarer these days, and it most certainly did exist in antiquity just about everywhere because of the laws of the ancient tribes.
Problem with this assertion is that it begs the question: Where did those genes in antiquity come from? Who knows who was "mixed" with other races? Are Gauls more Ayran than Germans? Are Georgians (who are genetically distinct from Europeans) from a purer stock of Whites lost to time? There's no way to answer these questions, and it looks like a distinction without a difference.
It reminds me of the debate between white sugar made from sugar cane or beet sugar. Sugar cane and beets are two very different crops, yet the white sugar they can produce is identical, both chemically, taste wise, and physically. Only with an intense molecular examination is it possible to tell a difference. For all practical concerns and purposes, beet sugar and cane sugar make exactly the same kind of white sugar. Is there is point to distinguishing the two as one being more "pure" than the other?
If someone looks, talks, acts, and thinks like a White, but then you find out that person is only 5% White, you would be very surprised, but you wouldn't call that person non-White. This is of course an extreme example, so a more realistic example of a White who isn't "White":
50% or less White, yet how many are aware? And would anyone really think of Keanu as non-White? Seems absurd on it's face.
If you are legally discriminated against in the west, then you are White. If you get special benefits, for not being White, then you are not White.
Exactly right, because the US Government, like 99% of people, classify people by their phenotype, which has NOTHING to do with racial purity.
Someone can easily be a White man, as shown above, yet not actually be "original" White in the DNA department. This is because there are many ways to create Whites, God obviously put Whites into the fundamental DNA blocks of human biology, and it makes you wonder just exactly what sequence of DNA will make an embryo phenotypically White.
The only real explanation that fits the data is that "Whiteness", like "Jewishness", is carried alongside autosomal recessive genes. This means race mixing cannot destroy a race unless there is an extreme amount of race mixing. Hybrid vigor will always be a present force in all raced mixed couples.
I believe this is why the strategy to destroy Whites went from promoting miscegenation to simply "abort all your kids for your career." And this is because miscegenation as a strategy doesn't work. Race mixing can produce both hybrid vigor or outbreeding depression, so, it's not a bullet proof strategy to hurt Whites, whereas not having children is of course a guaranteed kill shot.
