Not an exact match but good enough: Hagen Rether about spinal cord racism

Sorry, I'm not able to find a good English transcription. Basically what he says is: Fear of the foreign, the fear of the others outside of our group is imprinted into our reptile brain. It may have been an evolutionary advantage back then to keep your tribe together and your gene pool alive. And it's still in all of us.
If you act on this, you just show a lack of culture and education. It's normal to know that fear/ that impulse but then the thought: Wait a moment, that's my spinal cord talking, I should use my neo cortex has to show up. It's important to take that step.
