On what timescale? If district I'm talking about went 100 years red then 100 years blue but retained the same characteristics, that would be aggregate fairness, but clearly unfair. In your case of one red person in a sea of blue, it's obvious that they would be at a disadvantage. The situation I'm specifically talking about is one where red and blue are roughly equal. Does it make sense to randomly remove one side's voice?
