    The podcast does more to identify the strawman, which in my mind is the easy part. My boss and his boss regularly and purposely use this technique to shut me down when my arguments are backed by simple facts. I was hoping that the defense had some stronger techniques rather than saying, “That’s not what I said”. It makes the defender sound weak. One of the few counter techniques I found by google-ing was to use charity, but I didn’t understand what that meant. Have you since found any better techniques to defend against the strawman?
