Oh god ^this. There is a particularly broken specimen of human on a skeptical website who's username reflects his obsession, "Sfseaserpent". He believes that there is a sea serpent, essentially a biblical dragon, living in the San Francisco bay. There is no amount of debating or reasoning which can move him one iota, and the most you can achieve is to cause him to stop acknowledging your existence for a time.

I have had experience elsewhere with someone who trolls various forums in an effort to spread the "good word" about Jehova. Sometimes, "The only winning move is not to play." It's not always the case, and sure, that line can be used as an excuse by people in bad faith to avoid an argument; it's still the prudent course sometimes.

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.
