Slavery was NOT the creation or work of Islam. Neither did Islam depend on it to attain its supreme outreach that extended beyond Arabia. Islam emphasized the need for equal treatment for those who were already slaves, and even then stressed to free them.
Slavery was used as a vital tool by Christians of Europe, later Americans for extensive labor, cruel treatment, and often rape of the female slaves by their white master. While if an African slave was found to have had any relationship with the white woman, he would be punished severely.

Particularly since Islam practiced slavery centuries longer than Europeans, allows for slavery in its texts, its prohpet owned and sold slaves, slavery continues in Muslim countries to this day and you have idiots lilke the author of this op-ed and its supporters who call for a return to slavery.
