Is sci-fi one of the few genres to accept non-white characters as heroes?
Dorian, Almost Human
Sci-fi is one of the few areas in which non-white characters can be main characters in a narrative not focused on slavery, the civil rights movement, tropes like Ethnic Menial Labour, Apron Matron,Mammy and Whoopi Epiphany Speech, or some other form of racist commentary. Exceptions include those films and TV shows with entirely non-white casts.
