Here is a typical statement, this one from Priscilla Dass-Brailsford's paperback book "A Practical Approach to Trauma: Empowering Interventions" pp10 under slavery:
"In 1619, African slaves were first sold as property or traded into bondage, then shipped to the United States."
This is a fact, but slanted. The British American Colonies and later the United States, received only 5% of the slaves.
