A Theory about Trolls

I'm sure that most people on the Internet have encountered a species of troll who invade a discussion forum normally inhabited by the Other Side (from the troll) and have two beliefs that you would not normally expect together:

• The Other Side is full of ignorant morons who refuse to find out anything about contrary opinions.
• He (the troll) is thereby relieved of any responsibility to find out anything about the Other Side's opinions.

I suspect they're inspired by trolls from Other Side. (Their existence just proves the Other Side consists of morons.) So you might have a religious troll popping up in a discussion of dinosaurs saying “If monkeys changed into men, why are there still monkeys?” This will inspire an atheist troll to pop up in a religious discussion asking if God hates shrimp. That, in turn, will inspire a creationist to assume no scientist has noticed that the Second Law of Thermodynamics shows that everything must decay …
