Conversations about odd points of views and things that presently don't matter much in our lives gives us space to use our critical thinking and conversational skills. So even if these conversations don't lead to complete conclusions and spiral out of the realm of what the original points were just having time to go through the motions and speak openly and debate your peers can be super beneficial in my humble opinion. Plus it's fun! Who wouldn't want to talk about the complications of fictional magic in the real world? Or about the pros and cons of candy packaging?
