The speaker is angry, but at least he got his facts right. Islam has no particular color. It comes in all complexions; white, black, yellow, brown. The black community through America needs to learn their full history so they can move on in life and stop getting reeled back into Islam.
It is indeed Muslims who ruined the progressive Africa. It’s Muslims who are the founders of the African slave trade. Although slavery existed long before Islam it never actually existed to the enormous scale that slavery was created by Muslims, and never as an international export industry. It was Muslims who (force-) converted African kings to Islam which eventually lead to the Sharia-compliant enslavement of over 140 million Africans from their own continent to be sold like cattle to the rest of the world. Tempted by the enormous wealth earned by African kings and their Muslim slave sellers, trade envoys from around the world wanted a piece of the cake and began engaging in the trade. At one point the whole world was engaged in slavery. To compare the scale of the Muslim slave trade versus the much later American slave trade, about 300,000 African slaves got shipped over to North America in total. Muslims, however, captured and sold over 140 million of African slaves.
For over 1,000 years it’s mainly the Europeans, Japanese and Chinese who tried to abolish slavery. There were no attempts by neither African kings nor Muslim leaders to abolish slavery. Muslims enslaved not only Africans but people from all cultures. During the Barbary attacks on Europe alone between 1.0 and 1.25 million European Christians were enslaved by Muslims on the Barbary Coast between 1530 and 1780. That doesn’t tell us what the total numbers were between 620AD to 1920 when Muslims were continuously committing attacks and slave raids on European shores. However, since Africa was under Islamic rule with converted native African king’s, it was much easier to pick slaves from the African continent when the ruler was part and parcel of the entire trade. Muslims referred to African slaves as “dumb animals” and argued that Sharia law entitled them to take them as slaves and treat them as property. Even to this day, at least 6.4 million people are estimated to be enslaved in contemporary Africa under Islamic Sharia to Muslim slave owners.
