Lmao this show

>Slavery
In the show it is shown that dog people exist, simultaneously "pet" dogs exist. Pal is Arthur's pet animal. Multiple times pals intelligence is shown along with other animals. I deduce that these animals are either kept as entertainment slaves or considered some sort of 3rd of 4th class citizens or not even considered people to begin with. lol

>Anti race mixing (based?)
Not once in the show are hybrids presented. A few reasons could explain this phenomena. Genetic barriers such as chromosome count could prevent the successful reproduction of two separate species and therefore you wouldn't see any child hybrids. Social dogma could prevent the pairing of two foreign species. Mixed species couples would be shunned from society due to their affront to nature and god. People are probably killed for engaging in such behavior. Hormonal differences could prevent attraction.

I will ignore the pro lgbt agenda simply because it is propaganda from you know who

Also arthur is black because he is an ardvark and those are native to africa
