A discussion in good faith means treating the person you are speaking to with respect. It means not having ulterior motives. If you are having the discussion with the explicit purpose of changing their minds or, in your words, "alarming them to take action" then that is by default a bad faith discussion.
If you want to discuss with a pro-AI person in good faith, you HAVE to be open to changing your own mind. That is the whole point of a good faith discussion - but rather, you already believe you are correct, and are wanting to enter these discussions with objective ammunition to defeat somebody.
How do you actually discuss in good faith? You ask for their opinions and are open to them, then you share your own in a respectful manner. You aren't trying to 'win' you are just trying to understand and in turn, help others to understand your own POV.
The problem is it's incredible rare to find others that are willing to change their minds in return, so every discussion either involves you changing your mind, or the other person getting agitated.
