“… all Americans are slave masters because we allow to live in bondage, according to the Global Slave Index.”   
Oh yes some ‘majority’ American bought 57,000 African as the slaves and work them as the slaves.
However, look how ‘majority’ American still being a slave masters & treat African Americans, the whole justice system, treat them like the slaves.  I don’t see too many ‘majority’ American in power working to change slavery justice system.  
Let’s just look Catholics, the most of ‘majority’ priests and nuns practice racial prejudice right in the church and even during the mass.   
Do you believe God created all people in the image and likeness of God, or only the white Europeans? Do you realize Christ was a dark skinned, ‘minority’, middle easterner not a white skinned European?
I caution you not to rely or brag about your high IQ, you might end up with human’s puny IQ and miss divine wisdom.
