Nope, it was those who decided that those black slaves were not equal to a full person.
Having slaves is one thing (well, a bad thing) but to justify your need for profit and THINGS by trying to make your slaves part livestock, and not fully human goes too far, in my book.
Be as honest as the Greeks, Egyptians and Romans. Yeah fucking Jews were slaves, but they still need accommodations to grow children, be sheltered, fed and watered well and guess what - YOUR children will have even more slaves.
