TUCKER CARLSON (HOST): I actually agree that slavery is America's original sin. I think it has had consequences that have rippled through the centuries. But the question is what do you do about it. Because it's actually not a very racist country. We've had a ton of intermarriage and even more immigration over the 150 years since slavery ended.
