I Meet the Dumbest People - Ever

This is, well, I don't know what this is. Let's just say that "this is", and see what kind of soggy mess we have at the end. Oh, if you're not mathematically inclined, don't worry, neither was this guy so it doesn't matter!  HA!

So, on youtube I'm having a discussion with some dipshit, and he's trying, essentially, to back me into a philosophical corner of some variety. At first I thought maybe he's a dualist, but it didn't quite fit. So then I started to suspect solipsist as the likelier candidate; I'm still leaning in that direction and eventually you, dear reader, will understand why.
