On another forum I go on they have a debate league where it's 1v1 on certain topics and there's judges that judge them. The judges don't know who's debate they're reading and they pick which one is better. There would be different categories in the league and you sign up for which one you want to sign up for, you usually want to pick topics you're interested in...for example:
Futurama- Will debate MLB, NFL, NHL, NBA, general sports happenings
Will not debate soccer, and "minor" sports
That is just an example of a sign up. Other categories would include politics, entertainment, history, religion, philosophy, etc.
If I get enough interest I will post more about this. So please post on here if you're interested. There would be "showing" a month, meaning a "show" with 4-6 debates in it. (1 from each league, or 2 from some depending how many are signed up). There will be different judges for each "show", the judges would not be allowed to debate in that show, but they would be allowed to in the next show and won't be picked as judges.
