Someone shared this video with me, today:

And I felt like it's a concept that could be super useful for us all in this forum.

I've learned a lot about arguing in the last few days from both trying to awkwardly participate and sitting back and watching.
This video was like icing on the learning cake: a great view of the mechanics behind heated debates.
(I'm sorry if someone has already shared this video somewhere)
