Explaining belief in the absurd

[The Stranger]

- Holocaust denial, as in "Auswitzch was a happy place and the Nazi's didn't kill a single jew", not those playing the numbers game
- David Icke-ish beliefs
- ZetaTalk
- possibly Eurabia and other similar theories(very undecided though)

What I would not consider absurd are things like:

- religious practices
- new age people
- "normal" paranoia over security services like Mossad or CIA

any reason why you would call the former absurd and the latter not? or is that for us to disect? just wondering.

aparantly being absurd is being grossly unreasonable. if you take being unreasonable to mean being irrational and being irrational to mean that people who act in a way that is inconsistent (for example doing something counter- or unproductive) with their other views or goals believing or doing something absurd would be the following: have the goal to get to play A in the fastest way possible and then knowingly take the longest route to place A. Or since doing something absurd is grossly unreasonable thus grossly irrational it would be a more extreme example such as believing that killing people is bad and worship Stalin as your personal hero.
