Mythical place to argue with people:

1. Your anonymous or whatever you say can't be used by another party against you.

2. There is a code of conduct that is strictly held (no interrupting, no ad hominem etc)

3. You can ask for time-outs and think before answering.

4. There is a bank of known knowledge that is considered true, very strict standards, as unbiased as possible, including confidence scales.

5. You are face to face.
