The guest on his show is reciting eugenics, or "scientific racism." Joe is either unprepared to challenge this disproven theory or unwilling to challenge it. I am not sure. But Eugenics got 6 million Jews killed by Hitler and is the basis of much of American racist policy and racist attitudes historically. It is the basis of racism all over the world. He can have any guest he wants but if he can't engage and challenge a guy like that on such a dangerous, sick scientific theory, he needs to hire someone who can read the views of his guests before they appear. I personally believe in engagement if a person is sincere in what they are doing but that kind of misinformation is destructive and frankly, an outright lie by that guest.
