first blacks were not people, but property. then they were 3/5's of a person, then they were a whole person.
humans are fallible and can make amends for their mistakes. god is an omniscient observer, imho.
You're confusing 'blacks' with 'slaves.'
At the time of the founding, there were more than 100 black property owners in Virginia, that were considered full 'persons' and many of them owned black slaves, that due to their bondage, were not considered full persons. Anyone who was a slave, regardless of their skin color, was not a full person.
If this is your level of understanding, you really should stay out of discussions like this.
Most of the people on this thread actually know what they are talking about.
