Impugning judges in public is one of the stupidest things a field trialer, pro or amateur, can do. It changes nothing and pisses off not only the judge or official that was vilified, but also whomever asked that person to officiate. Any pro that publicly disparages a judge is a LOSER, in my opinion and I would not put a dog with them. Also, not every person has the moral backbone to ignore an A$$hole handler and just judge the dog.
If you do not agree with a judge's evaluation of your dog....don't run under them again. Simple. If you don't like the judges a particular club picks or the terrain the trial is held on...don't go there. Simple.
