I honestly cant definitively say where the story is going but the lack of care given to such an important topic is telling me... its not gonna be good

If you're unable to recognize that an author writing 'i am your humble slave, master' during a time when enslaved people faced being tortured, sexually abused, and were psychologically tormented is racist... nobody cant help you.
