... That's just nonsense. Normal scientists working in genetics don't believe in race. The field has moved on from the 40s. It's not a conspiracy, there's just no evidence, because why should there be? It would be very surprising if a bunch of 19th century racists had accidentally discovered a deep truth about genetics before anybody had even discovered DNA.

Honestly, you just sound like you're a racist. Which is sad, but it's also indicative of a lack of common sense that you expect the universe to conform to your prejudices.
