To have a productive discussion, you need a method of discussing. What is step 1 in a discussion? What is step 2? What is step 3?
If you don't know, or don't have it in writing, why would you think you're ready for an intellectual discussion? That means you will follow a unknown or unclear method. In that case, if the method has any flaws, then you will have a hard time in the discussion (due to using a flawed method) and have a hard time understanding why the discussion isn't working well.
If your discussion method hasn't been analyzed with conscious, critical thinking, you should expect it to have lots of flaws. And if it isn't specified in writing, you should expect to change it mid-discussion according to your biases.
