The main argument seems to be that the Founders were well aware of the problem of gerrymandering but gave the task of creating districts to the political branches anyway.
Begrudgingly, I tend to agree with the SCOTUS decision. These are political powers given to the other branches and not to the courts. We could have a situation where each and every districting map is brought in front of the courts, and they don't want to be in the business of second guessing every single state legislature with an eye to political parties. I think the courts can step in when it is a question of race, religion, or other protected groups. However, political parties are not a protected group, as far as I can tell.
Having the courts involved in redistricting was never a long term solution. The American people need to stand up and fix this through legislation. A grassroots (or astroturf, who cares as long as it gets fixed) organization could work on some standardized language that could be put on state ballots across the country. If it is pushed as being non-partisan, it could be effective. A similar campaign has seen Obamacare Medicare expansion voted into law in the most conservative states.
However, Republicans know that demographics are against them, so they would use scare tactics to get these ballot measures shot down. Still, it is a hill worth dying on, IMHO.
