I'm actually not sure how much people in general dislike slavery. They probably do to some extent, but the actual reasons slavery is not generally done (of humans) are quite complex, including hundreds of years of various philosophical arguments, economics, and logistics. If you ask someone if they support human slavery, they probably know or can imagine the conditions involved, put themselves into that situation, and dislike it. It's much harder to put yourself into a model running on a computer somewhere, even if you intellectually think it should have rights to some extent.
