Read the book islam's black slaves by ronald segaL,and you will see how evil islam can be.
Arabs used to buy african women around eaastern africa and use them for sex slaves and from what I heard it still happaens quit a bit around ethiopia.
I would not doubt saudi arabians buy little boys and use them for pedofilia.

read the reviwe and interview of islam's black slaves

slavery in eastern africa started around 700AD when they started trading slaves around what the arabs call zanji.
Zanji became another word for blacks thus zanjibar.
there are still scattered populations of desedants of slaves in iraq,kuwait,jordan,palestine,which many palestinbeans are actual desendants of african slaves,iran,and other places espcially saudi arabia.
