@Kaarme okay, I'll agree with you, but there are a group of slaves who don't even know the word, never mind the meaning and those people are the african pygmies. They have an average IQ of less than 80. They've suffered genoicide, slavery and more because their average IQ if 4+ points or more away from the average non pygmy african. But that is not too important, just thought i'd share. I do think Japanese authors treat beast people as being subservient to humans just in the same way that dogs, horses, pigs and a few other animals are to us. Do they think if you treat your slaves as friends that its okay, lol? I still understand that a slave is the only person you can trust when you're dropped into a new world if there, more so when there is magic in place, though building trust with a slave ain't hard if you improve their condition, treat them like an equal and ask their opinion.
Besides north korea china and africa I would say that the tracking of people is improving such that human traffickers are being caught more often which is good to hear. I just hope the bad guys don't find a new way to sell people. If there was death penalty for buying or selling slave, being involved in the sale of humans and or kidnapping of humans with intent to sell them into slavery or at least life in prison without a chance to get out unless its in a coffin as they should be given the choice of suicide.
