At least the topic of oppression is addressed, and until this episode it's shown as a real problem/oppression. (it's oppression against "faunus", people with animal ears/limbs). But in episode 16, the suffering from one of the main characters, which is a faunus, is compared to another main character's suffering, which parents got hurt in an attack from a faunus organisation because they are really wealthy and are an important part of the oppression. I find this concerning.
