Things believers find most offensive...

[JimC]

Calling it "the babble" or "the book about the super magic sky daddy by the stone age sheep herders"

The Bronze Age Goat-herders' Anthology of Campfire Tales for Boys: God's Little Instruction Manual for Handling Slaves, Sex Slaves, Kitchen Help, Naughty Offspring, Babysitters and the Soon-to-be-extinct Tribes Next Door. Now with The Egomanical Hippie and His All-Boy Posse Hang Out in Palestine.

Now with added naughty-child-eating-bears and beasts of the Revelation!

And naughty bits.

Only nookie in the babble is where the super magic sky daddy told 'em to rape all the women after they killed all the men. It doesn't go into detail.

[Schneibster]

Now, I'd argue it's an allegory of any number of things besides that. For example, some sources will tell you it's not about man and woman at all, but about the relation of a person's soul to Jehovah.

No nookie there. Nope, nosir.

Sure, take all my subtle.

[Hermit]

"The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully."

This truth does hurt, I suppose. Who would be pleased to have been found out worshiping an arsehole like that?

Telling them their bible has one too many books.

[Hermit]

Telling them their bible has one too many books.

...while they merrily cherrypick from the lot.

Oh, and they feel offended when you tell them that they cherrypick.

Edit: did you say one too many? The old testament alone consists of 39 books, the new of 27. That's for protestant christians. The catholic bible has an additional 11.

I see bumper stickers here that say, "Nobody needs more than one book." Makes me wonder where the tech manual for their car is located in their bible.

[Svartalf]

Car repair techs are nobodies anyway

[Gawdzilla Sama]

Accommodationism.

[Horwood Beer-Master]

The idea that there is a single objective reality - that the universe is purely material universe - and that their very thoughts and experience are a product of an evolved material brain which is but a part of this material universe, and not subject to any special exemptions from the laws of physics, nor intersecting with a "spiritual plane". And that "dead" means their ain't no "you" anymore - except in a purely past tense for other people.

I've never tried debunking the fact that the Pascalian Wager wrongly assumes chretinity as THE religion to follow to a chretin... After all, what if the RIGHT religion is islam or buddhism? you'll have lost your wager anyway, following the dictates of a religion, but without benefits because you picked the wrong one.

Never mind all the actual existing human religions - what about all the other infinite possible such systems that one could imagine - or indeed the ones one couldn't imagine.
Each of these has equal validity as christianity (i.e. none), and for each you can think of, there must an exact opposite. Ultimately all such 'bets' cancel out. There's as much chance (again - none) that turning round on the spot anticlockwise 4 times before going to bed, sorting your socks by age, and touching your left little-finger to the end of your nose whenever you see more than three members of the opposite sex at a time will get you a ticket to a preferable afterlife as following the dictates of christianity or any religion. Or as someone on Qi once pointed out - what if it's the Atheists who get to go to heaven?

Penises, vaginae and anuses.

Odd considering many believers are either dicks, pussies or assholes.
