I think my league was very abnormal however as we had a lot of layman, parent judges that we had to teach rules to (and sometimes the teams had conflicting interpretations), and we didn't allow more abusive techniques such as speed and spread (a common technique in Policy or Parli to present arguments as quickly as possible to prevent the opposite team from being able to address all of them, resulting in a de facto win). We would never have allowed someone to judge with a bio of "I will no longer evaluate and thus never vote for ... fascism good, capitalism good, imperialist war good, neoliberalism good, defenses of US or otherwise bourgeois nationalism", and it's insane to me that this was allowed at a top end tournament. There were certainly judges that brought their own priors (and we tried to keep track of them to help the rest of our club out), but they generally didn't announce it in such a damaging way.
