all redistricting is gerrymandering. all of it is to some purpose.
if a state is 54-46 dem or rep would it be “unfair” to draw every single district 54-46? it would be a representation of the state. the outcome may be 100% one party, outcomes are not guarenteed. how about drawing them so that 5 districts have 80% one party and 4 80% the other. now you have a gaurenteed “fair” distribution of seats, and a completely polarized electorate thats actually less representative of the whole. no matter how you draw a district you are designing it for a desired outcome.
