[on why "argument from personal incredulity" isn't a logical fallacy]
How's it a logical fallacy? Logic is by definition a consideration of incredulity. And incredulity is by nature personal. Therefor logic IS personal incredulity.

Um, no.
Logic is a position based upon empirical evidence and rational, considered appraisal of all aspects of the issue.
An argument from personal incredulity basicaly states that the speaker can't or won't believe that something could ever be true, so therefore it can't be true regardless of evidence. The logical fallacy can also go in reverse by refusing to consider a negative, and asserting the positive as a result.
It's a logical fallacy because it is based on belief without evidence.
NB Sandman: logic does not require empirical evidence. It's just a way to evaluate statements for truth and consistency.
For example, the following is logically valid:
P1: All Christians have beards.
P2: David is a Christian.
C: David has a beard.
It's not true , but it is valid.
Of course, in order to determine whether something conforms to what happens in the real world you do of course need some empirical observation!
As for personal incredulity, this page explains it quite nicely.

Not according to any dictionary I've ever seen, nor according to any person I've ever met who speaks English.
This must be an instance of the Fundie Word Redefinition Project.
Udsuna's arguments aren't nearly as bad as many we've seen here, I think; it's just that his premises are based on many underlying unproved (or even disproved) assumptions, some of which may be yet unverbalized.
But this one, in particular, is a doozy. I'd say that at this point, he was either tired, feeling desparate, or just trying too hard. Redefining logic to suit your argument instead of recasting your argument to fit logic? That's going too far -- to Kansas, in fact.

Yes, yes they are. He's the worst fundie I've ever seen (I'm the one that's submitted all these, and read tons of posts by him).
Raistlin: Okay, well, I'm sure you're more familiar with his work than I am. Perhaps I'm just too dazzled by fairly decent grammar and spelling (rather rare among the fundies we see here) to be objective here.

Despard, you are correct, I mis-spoke. It should have read "Logic is a position based upon empirical evidence or rational, considered appraisal of all aspects of the issue."
My bad :)
“How's it a logical fallacy? Logic is by definition a consideration of incredulity.”
No it fucking isn’t. Logic is a tool to evaluate ideas and remove personal impressions, leanings, tendencies, and credulity out of the analysis.
Using personal incredulity is just your feelings. It’s NOT logic.
"And incredulity is by nature personal.”
Exactly. If you grew up being told by your father that no one ever went to the moon, then you would resist physical evidence and logical proof of the moon landings, based on your personal feelings. That’s illogical.
"Therefor logic IS personal incredulity.”
This is not a logical argument. You’ve accomplished nothing but restate your personal feelings.
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
