T-Rex: Let's say on a given matter there are a variety of opinions - correct and incorrect.

T-Rex: However, given the nature of correctness, there can only be a SINGLE correct opinion!

T-Rex: Therefore, since every opinion that is not the correct opinion must be incorrect, it follows that the overwhelming majority of opinions you encounter will be - MUST BE - incorrect! And given that conclusion, how can we trust anyone or anything - even ourselves! - when we know most of what we say and believe must MATHEMATICALLY be wrong??

Utahraptor: Except that opinions can be partially correct, exploding this entire theory!
T-Rex: What?

Utahraptor: If it's 10 degrees out and I think it's 11 and you think it's -10000, we're both wrong, but my opinion has more merit. Some opinions are more correct than others, which means they can't all be dismissed en masse. Sorry dude. I know you were looking for a shortcut to reasoning here.

T-Rex: INCORRECT, my friend!! I was ACTUALLY looking for a way to feel better about all the incorrect opinions I hold, such as for example that the Ghostbusters cartoon with the gorilla is the best one!
Off panel: Dear God.
T-Rex: I KNOW, I KNOW, I CAN'T HELP IT??
