He is so confident that he might just be a troll. If he isn't he is probably the greatest example of being confidently incorrect who I've seen posted here in a while.
I really wondered that too! Not sure how anyone could actually be this obstinate in the face of overwhelming evidence to the contrary. Might very well be a troll lol
Nah. I know people like that. They just shut down and reject everything that doesn't align with their world view. No point even arguing with them at that point, just let them live in their clown world.
