Some people are very organized and structured and see the world in a very binary, allegedly logical, way. However sometimes the yes / no binary response is laced with a ranting tirade which defies logic and pushes the binary decision into the realm of ridiculousness. Indeed, the very goal of a binary person being able to make clear decisions becomes clouded when binary extremism takes over, and the person's opinion, decision, argument etc. is rendered moot.
My normally logical co-worker often lapses into fits of binary extremism when annoyed by a customer.
