Usama Dakdok led a series on Islam and slavery that has grave importance. Kristie Johnson and myself were present to assist. Sadly, there are many who wish to hide these important facts in order to push their own personal agenda, which requires "obfuscation of facts." Obfuscation is a deliberate act of hiding something. This is purposeful jump over information, or misdirection away from that information.
Slavery in Islam is found throughout the Quran. Muhammad himself was both a slave owner and a slave trader. Yet, the lovers of Shariah, known as Muslims insist that Muhammad was a perfect man.
