It’s somewhat intellectually dishonest to blame the institution of race-based slavery of blacks on Muslims.
Islam has always been in favor of non-discriminatory slavery. Muslims enslaved people of all colors, raiding European ships and coastlines and into southeastern Europe well into the 18th century.
Muslims stopped enslaving white Europeans simply because Europe became too powerful and slave raids became unprofitable and dangerous. They (mostly) stopped enslaving black Africans because the powerful white Europeans forced them to, in an outrageous example of disrespect for the cultural traditions of the Other.
However, one could make a reasonable argument that citizens of vassal states such as Communist Korea, Cuba, China are essentially slaves to the ruling elite. The situation is technically the same, although the slaves are better treated, in socialist states such as the EU and Oba Mao's Amerika.
