If a theist says an atheist has no soul, and is speaking literally, the theist would be wrong and the atheist wouldn’t care. (Theology, as generally understood in Western thought, assumes a human soul, so to say that someone literally doesn’t have a soul is to misstate known theology.)
Speaking metaphorically, I’ve known devout Christians who were soulless, so that would be an individual judgement.
As an atheist, I resent the idea that I have no soul. I can boogie down to the Motown beat with the best of them.
So we atheists and the Borneo savages who have never heard of the church are doomed to charbroiling for an eternity due to how we were born. Add in Muslims who have been raised in the dark. Add in most of the worlds population. To some, if you don’t accept Jesus as your savior you are doomed. When most of the population has never heard of this ,how do you evade that it is cruel and unfair.
What the church does when faced with contradictions is it tries to invent a workaround. A special case to explain it away, knowing full well the blind followers will accept anything as truth. The fundamental cruelty cannot be ignored. To have polite discourse with someone who says not believing like he does will result in an eternal boiling is difficult. I offer gentle jibes . You counter with eternal damnation.
How do you know how many souls a person has? He could have a million for all you know.
Sorry, man. Satan used to be in the business of buying Doper souls – RT Firefly, Fretful Porpentine, and I were present when he closed the deal by making payment on one – but the Admins. exorcised him. 
The only thing I see being burned, here, are your straw man claims. There are certainly Christians and Muslims who do believe what you have posted, but their numbers on this message board are in the single digits (which may be as low as 0).
If one wants to get fully technical – and I reference C.S. Lewis’s The Discarded Image as cite for this – medieval theologians considered that the soul was that which was the mark of a living thing. Plants had a vegetable soul, enabling them to grow and react to sun, rain, etc. Animals had an animate soul which added to the characters of the vegetable soul that of movement and sensation. Humans had a rational soul subsuming the characteristics of the vegetable and animate souls and adding to it reason and a moral sense. It was an integral part of being a living thing, not something you had but a part of what you were. And mswas’s interlocutors were either unaware (or rejecting) of their own faith’s theology or intentionally being insulting.
I believe the social implication is that atheists have lost their souls because they don’t believe in God and therefor will not experience eternal life.
BUT…
That, of course, is not true. Equating soul with spirit, one can not posses a spirit because one is a spirit, and neither can one lose a spirit which would amount to losing themselves.
Just more doctrine, what can I say?
Are you taking the question in mswas’s OP to be Christian doctrine?
I have this vision…
… an atheist is on his deathbed. Soul-less of course. 
But lo! he converts just in time. 
An angel is rapidly dispatched with a soul. 
But the angel is delayed, and arrives too late. :eek:
It’s quite interesting how the mess is finally sorted out. 
Coming soon to a theatre near you… 
So I’m at dinner with a couple whom I know only casually, Tom and Mary, and they are theists. Tom finds out that I’m an atheist, and he’s curioius, so he asks me what happens to my soul after I die. Helpfully, Mary points out to Tom, “atheists have no soul,” meaning that we don’t believe we have them.
That’s actually how I interpreted the OP, that it was a situation like this.
Hmmm…I always figured they thought we all had souls, but ours were unworthy or unlovable or something.
Kalhoun There are many atheists whose company I would prefer to many theists.
I was thinking more in terms of unlovable in their god’s eyes.
Well, that’s what I meant, that they thought we had a soul, but Mary in my example was explaining to her husband that I wouldn’t be able to answer his question, about what happens to my soul, because atheists don’t believe we have them.
I think asking atheists what happens to their souls after they die makes as much sense as asking non-Scientologists what happens to their Thetans when they die.
Only if they are the sort of atheists who don’t believe in souls; you are confusing materialists/physicalists with atheists.
We don’t have a SOUL!?!?! I better punch my give-a-shit clock.
Got it. You can’t tell what happens to something you don’t have when it doesn’t die. Ouch! Kinda makes my brain hurt a little.
Hmmm…Interesting take on it. I always thought that the only purpose of a soul would be to have something for god to take when you’re done with it. In other words, I’ve never heard of a “soul” outside a religious context; therefore, you could only discuss it within a theist/atheist context.
Out of curiosity, does anyone in this thread believe a soul exists outside a “god” context?
