Excellent video at link.
In the video, Mark Steyn quotes the late Senator Robert KKK Byrd, D-WV:
I shall never fight in the armed forces with a negro by my side ... Rather I should die a thousand times, and see Old Glory trampled in the dirt never to rise again, than to see this beloved land of ours become degraded by race mongrels, a throwback to the blackest specimen from the wilds.
— Robert C. Byrd, in a letter to Sen. Theodore Bilbo (D-MS), 1944[11][18]
