Judges screw stuff up all the time. Which is why trial courts get reviewed and overturned by appellate courts. Which is why appellate courts are reviewed and get overturned by supreme courts. Some judges are just bad judges, and get overturned a lot. There is practically nothing you can do if they are elected, except point out the stupidity at the end of their term and hope they don’t get reelected. Judge Cannon, on the other hand, was appointed for life - and it takes conviction by the senate after a house impeachment to get her off the bench.
So while I share your frustration, I will await your solution to the problem. Texas has more than your fair share of idiots, clowns, dishonest grifters and incompetent ideologues as any state in America, yet you do nothing about it. Or maybe you can’t do anything about it. But going off on the legal community for not solving the problem of Judge Cannon is like going off on Texas for not solving your fill-in-the-blank politician problem.
Sometimes things are just hard and unpleasant and depressing and the problem can’t be pegged on a small subset of folks.
