In Futurama, there are large numbers of mutated humans on Earth, who are treated very poorly. They are an underclass, figuratively and literally.
Is there ever any explanation given for this? Completely alien species (like Kif's people, or Zoidberg's) are treated fairly and equally by most people, but mutants are not.
A certain female character who is revealed to be a mutant was even disguised as an alien in order to prevent this bigotry from affecting her.
Is it ever explained why mutants are so hated? Don't the people of Futurama enjoy X-men as much as we do?
