CIRA international get racial; Islam against blacks?

In answer to the video "The Unknown History of Islam 07 - Islamic Slavery Introduction, Part 1"

Slavery wasnt invented by Islam or Christianity, it existed long before. In ancient times almost all nations from the Romans to the Greeks regarded slavery as something natural. Aristotle thought that

"..some men are by nature free, and others slaves, and that for these latter slavery is both expedient and right."

The elites throughout India, Persia, Rome, the Arabian Peninsula, Romania and Greece regarded them as some commodity not worthier than cattle and had the power of life or death over them. The Judeo-christian scriptures hardly improved the status of slaves, as human traficking was allowed even if it involved one's own children. Severly scourging the slave was permissible so long as the beating did not immidiately bring about the slave's death Ex21:20-1.

The mosaic law, which Jesus abided by to the letter and instructed his followers to do the same, still allows purchasing them like any other commodity, detaining them and passing them down against their will Lev25:44-46,Deut15:16-17. Slaves can be forcefully seperated from their wives married under slavery, and from their children who are to stay with the master should the slave request and gain his freedom Ex21:2-4. By keeping his family as hostages, the master is almost sure to keep his slave permanently. For hard labor purposes, the only restriction to slave acquisition is that it was forbidden for Jews to enslave one another for hard labor. 

However, throughout history they could, and did, sell one another to slavery for a different purpose than their non-Jewish slaves, they were employed for works that did not involve physical toil Lev25:40-46. Solomon, during the building of the Temple and his own palace made ample use of non-Jewish slaves during 20 years of hard labor.

Slaves had to lookup to their masters as equals of God Col3:22-24, respect and fear them in servitude as they would serve Jesus Ephes6:5, submit to even harsh masters 1Pet2:18. So inconceivable is it that a slave may one day rise above his cursed status and gain responsibilities that the earth is pictured as quacking at the thought of it Prov30:21. The subjugation of a slave is an essential part of religion

1Tim6:1-4"so that God’s name and our teaching may not be slandered..These are the things you are to teach and insist on. If anyone teaches otherwise and does not agree to the sound instruction of our Lord Jesus Christ and to godly teaching, they are conceited and understand nothing".

As stated earlier, being nothing more than an ISraelite prophet in a long line of prophets, Jesus himself never banned slavery and in fact even endorsed unquestioned submission of slaves to their masters Lk17:7-10. Slave trafficking became an organized business through the Christian nations of Europe and America who captured slaves by thousands from their colonies.
They packed them like sardines in ships according to a precise mathematical calculation to maximize profit and many died on the way. Before leaving, the ships were blessed by priests. Christian priests themselves participated in the trade, especially in Angola, and justified it by saying they were baptizing them. Towards the end of the 18th century, some Arab nations participated in the slave trade too.

The end of slavery in the christian world did not come by the hand of the church. It was a handful of moralists who rose slowly against it. Their cries werent heard in britain until 1807 when it was no longer profitable to the economy and the governement wanted to cut expenses especially in the sugar plantations after they lost their global monopoly.

In pre-Islamic Arab society, slavery was also an established institution. Slave men and women were found in almost every house, their number was a symbol of status. They were mainly prisonners of wars, or even debtors who were enslaved, then distributed among the armies or sold in the market places like animals. They were a source of cheap labor and livelihood for thousands.
