@Inkpen,
I was under the impression you were Muslim. Do you know that Muslims were just as much a part of the enslavement of Black people as Christians were? Factually the Muslims started the practice of taking slaves from Africa (although the Christians joined in pretty quickly).
On the other hand, it is pretty difficult to find a religion that wasn't part of slavery. You might get away with Bahai, and one of the newer religions might work.
But becoming Muslim because the Christians had slaves is just stupid.
