Whites were slaves since the 7 th Century. Everyone's Ancestors were slaves at some point in time in human history.

 

The Balkan slave trade was the trade in slaves from the Balkans via Venetian slave traders across the Adriatic and Aegean Seas to Italy, Spain, and the Islamic Middle East, from the 7th century during the Early Middle Ages until the mid-15th century. It was one of the routes of the Venetian slave trade. 

The trade rested on the fact that the Balkans was a religious border zone, which was significant in the Middle Ages, when religion was the determining factor on who was viewed as a legitimate target of enslavement. The Balkans was pagan territory long into the Middle Ages. After it had converted to Christianity by the 11th century, it was influenced by Orthodox Christianity and Bogomilism. This influence maintained the region's status as a religious border zone to the rest of the then-Catholic Europe. The slave trade of first pagan and then Orthodox and Bogomil Christian Slavs were exported to Italy, Spain, and Portugal in Southern Europe, but the major part of the export went to the Islamic Middle East. 

Arabs / Muslims been trading white slaves since 909 - 1171. 

Far surpassing the US by over 550 years at least.  

Everyone's Ancestors were slaves at some point in time in human history. 

Let's move forward and not backwards. 

Amen
