@freemo Yeah, asking people to put their evidence on their table sounds like a pretty good idea.
But it does get frustrating when you ask if there has been evidence, and people were reply that there absolutely has, and what they present isn't evidence at all, and you point that out, and they say it is, and at that point there's nowhere else to go with it.
It's raining outside!
What's your evidence?
Well here's a bucket full of water from the rain!
...That bucket is empty.
No it's full of rain! Look at all this water in it!
Siiiigh
I refer to it as the book club theory. We all showed up to the book club, and we all read books with the same title, but the plot lines were different in different people's copies, so it's pretty darn hard to discuss the book.
