Since so few leftists has ever read the Bible (and those that may have count on the fact most have not) they are unaware of the fact that Slavery has been around since the beginning of civilization.
Most of these morons are unaware that Slavery Continues to this day in Northern African countries dominated by Islamists.
And, of course they are unaware that it is Northern African Islamist Countries that perpetuate the Slavery Trade to this day.
Slavery has been around since the beginning of civilization.
But not CHATTEL slavery which is a recent Islamic invention. This is slavey were the slave is of low value and has no rights or freedoms other than those permitted by the owner and which privileges are not recognised by the rest of the culture.
