Islam explicitly introduces and condones race based slavery so that is an integral component of their culture unfortunately.
And?
You do know who were the most enslaved people by Islam? It was white Europeans. And the Arabs even had a specific name for them. "Mamluks". Read here about the Mamluks: Mamluk - Wikipedia
The word Mamluk is Arabic for slave. It was used to describe Muslims of slave origin. And the mark of slave origin at that time was white skin. If you've seen any image of a Mamluk it's that of a white person. This is in direct contrast to the Arabs who at that time were defined by their black skin. And in most pictures were depicted as being black.
Here is a picture that shows what I'm saying:
The description below describes the two white individuals in this picture as Mamluks while it describes the black man as a "Bedouin". Bedouin was a term used to describe the pure Arab desert dweller.
The painter of the this picture is clearly telling us that pure Arabs (aka Bedouins) were of a different race than the people called Mamluks. The Mamluks were white while the pure Arab was black.
