They’re obsessed with it because they don’t like the common people. It’s as plain as the nose on Pinnochio. Elites like Ted Turner, etc. are sick creeps, and their narcissism, vanity, and arrogance has pushed them toward wanting a final solution, ultimately.
Much is made about how many Cluster-B psychos there are in White Nationalism, but honestly SJW’s or any other elitists aren’t any different.
Does IQ matter?
I don’t think it means much. Again, this is elites expressing their hate for real people.
