In my opinion, SCOTUS' decision in Louisiana v Callais is based on two flawed beliefs. First is that it is ok to make voting districts for partisan reasons, in other words, allow a majority party to create districts that favor their party winning seats. Second is the belief that racial discrimination is a thing of the past. I also have qualms with the idea that a majority can be discriminated against.
The refusal of seeing partisan gerrymandering and lobbying and very large campaign donations as wrong is evidence of a system functioning as desired by those in power.
