You're wrong again about what was in the ruling.
This ruling was not about allowing districts to be redrawn in a way that is partisan. Different issue, different topic, not the present case before the Court.
Perhaps you don't understand that the Supreme Court addresses specific questions put before it, and that wasn't the question before it.
THIS question was about setting districts based on race:
"The question before us now is whether compliance with the Voting Rights Act should be added to our very short list of compelling interests that can justify racial discrimination"
Partisan districting is not the question. You're getting lost in your own separate crusade.
