honestly the scanlator made a point that i believe but can't say anything about in the PC society... yes, slavery is bad, however from what i see, most of the manga that depict slavery explicitly tells us that slaves are guaranteed basic rights and must be fed, clothed and treated humanely. these kind of slaves aren't like the slaves from earth where they were treated like objects instead of humans, they are still human and have these basic rights. and if i may say this point here, criminal slaves, which most of these slaves are, is no different from indefinite penal labor and while it may not be indefinite, penal labor is still practiced by many developed countries in this world as a form of punishment. these slaves in manga aren't the same as slaves in real life (usually) so i don't see why many people criticize slavery in manga when it honestly isn't even really slavery (of course i don't agree with the child slaves that were sold by their parents, i don't agree with that at all.) The point is, just enjoy reading the manga people without adding politics into it, i just come here to enjoy myself with a dose of bad isekais and romcoms
