What we believe is what we filter of our inputs that we consider true.

Lots of folks can be exposed to the same ideas without accepting them, and once in awhile people really want to latch onto something.

I used to have an Australian dude that would regularly let me know American's didn't go to the moon, with all sorts of crazy things to support it. No amount of physics explanations about his ideas would get anywhere. Anything that disagreed with his ideas was filtered out.

I think the best way to deal with someone like this is not to disagree and argue - it won't work, but to instead fill them up with something better to have on their mind on a regular basis.
