Leftists don't seem to mind that Republicans gerrymander just like has always been done. They mind that Republicans seem to be good at it.
Yes, please tell me more about what I think. One second while I take all my thoughts about mathematically determined district borders (Cool and good but can do a bad job of combining disparate interests together in a way that prevents different areas from electing representatives that match their needs), scratch them out and scribble "lol nothing matters gerrymander this nation into the ground" over them in crayon. I could also revise my opinions on that putrescent waste of skin Scalia and recant my offer to dig a hole deep enough to hand him off to Satan personally over what he did to the Voting Rights Act. Thank you for shining your gleaming rays of wisdom upon me, I was truly lost as to what I thought.
However, I do specifically mind that they did an excellent job of it because it's yet another instance of the Republicans never turning down an opportunity to fundamentally undermine the faith in the government and its institutions when it'd give them some short term power.
Or, and this is a fascinating alternative to me changing all my opinions to match your justifications, you could stop being a dishonest idiot and engage in some reflection about what you support for once in your life rather than lying to people's faces about what they support. You currently support the active destruction of our democracy and our institutions. That's the sort of thing that separates us from the attempts at nation-building in the Middle East. Given the fact that you've turned your colon into a condominium for tarantula hawks about the general state of that region, I'm morbidly fascinated by how you seem to be all too happy to work towards importing their worst problems.
