This sounds like the textbook definition of trolling. If you honestly believe the sea serpent guy I think you're probably the one being taken for a ride. You're right with the Wargames quote in any case though.
I've never engaged with him personally, but having seen him over literally many years, I doubt that he's anything other than a sincere maniac. He's not good at getting a rise out of people... he always ends up being the one to lose his temper and flame OUT. Same with the Jehovah's Witness.
Trolls are there, all over the place, but there are "True Believers" too, and they're even more immovable and pointless.
