I think Terry Pratchett summed this thought up nicely in Men At Arms…
I use all the normal iterations on the deity and his son. I don’t think any more about their literal meanings than I think about thursday referring to Thor.
My twelve-year-old daughter does, constantly. Not sure where she picked it up, but any time I annoy her, she lets it fly at me.
“CURSE YOU!!!”
I actually use “Curses, foiled again” as a very mild exclaimation of annoyance.
I occasional think about trading in “Fuck You” for more inventive curses, to prove my superiority to those poor sods who are limited to the F-bomb. Unfortunately, “May your camel get fleas” isn’t very effective here. (That and I’m usually to slow to come up with something really interesting on the fly, and cue cards detract from the moment.)
It’s like ceremonial deism… Hmmm… ceremonial blasphemy? 
I say “Gods”, sometimes “Black Gods!”, “Dark Gods!”, “Elder Gods!”, “Great Old Ones!” or otherwise invoke the various Lovecraftian entitys, especially “Hastur! Hastur! Hastur!”. “Great Cthulhu!” and “Sonofa…HoundOfTindalos!” get a workout, too. Sometimes “Father Dagon and Mother Hydra”. If occasion merits, some irritant may get the full "Shub-Niggurath, Black Goat of the Woods with a Thousand Young!!!”
Maybe a better way to frame this question is, “Do any atheists or agnostics deliberately refrain from using religious-based swears?”
I’m not a Christian either (although I am religious), and I say hell, goddamnit, Jesus, and oh my god like everybody else, not to mention hostie, tabarnac, câlice, ciboire and the rest in French.
Expletives in high-stress/hammer on digit situations aside, I also ascribe to the view that to use religious-derived exclamations implies some sort of endorsement of that religion. As I am Anglican-raised, I still find myself saying “thank god!” automatically sometimes. However as I’m now effectively atheist, this sounds wrong to me (particularly one such utterance - “thank god I didn’t tell him that I’m an atheist”).
I try to deflect “thank god” to “thank Rod” which for convenience can be a reference to Rod Stewart. There is at least ample evidence for his existence.
Heh. “Goddamn motherfucking piece of shit!” is one that I use commonly. I was troubleshooting my chainsaw last night, and between “you son of a whore” and “Goddamn motherfucking piece of shit!” I had it covered.
btw: small crack in the fuel line.
So far as I’m concerned, they’re useful tools in my box of cuss words. God and Christ are quite similar to other profanity in sound, being single syllable with hard consonant sounds on the ends. They have the advantage of being (slightly) more socially acceptable while not being as cheesy as ‘gosh darn it to heck’.
Me. Partly because of my disdain for everything religious; partly because that disdain makes religious terms unsatisfying for swearing. The very occasional “damn” is about it.
I don’t actually swear using the classic four letter words either; I was constantly abused in school by kids who swore obsessively, and this gave me a strong aversion to the classic swearwords. Pavlov in action I guess. I tend to say something inarticulate (“Arrrgh”, more or less), or something like “idiots!”. Oddly, at one point I found myself using my brother’s name (in situations that had nothing to do with him) as a swear word and had to break myself of the habit. Swearing seems somewhat reflexive.

I use all the terms listed in the OP, and I’m also a particular fan of “Christ on a bike” and “Jesus Christ on a crutch”.
Edit: I didn’t notice “Bless you” in the OP, I don’t say that, not because it’s religious but because it’s just… I dunno, stupid? I don’t need to say something when someone sneezes.
I use “you son of a whore” mostly on inanimate objects.
I’m having trouble opening the pickle jar, “Oh come the fuck on you son of a whore.”
I keep dropping the wrench, “Quit fucking around you son of a whore.”
and so on.
I don’t use the Lord’s name in vain. He ain’t my lord, but I don’t really intend to cause offense by swearing and these phrases would be considered too shocking to those who know me.
But I don’t hesitate with a “dammit” (while not thinking about the implausibility of literal damnation) and I’m pretty sure my last words are going to be “oh shit.”
I am agnostic. I frequently sound like Tony Soprano. In fact, I believe I came up with “Jesus Fuckin’ Christ” independantly of Tony. In a similar vein, I’ll also say “God fucking dammit.” I’ll also string curses together so they sound like one word as in “godfuckindammitfuckinsonofabitch.” I’ve also come up with some really blasphemic curses I really don’t feel comfortable sharing here, but they would really shock the hell out of believers. They are for times when I’m by myself and don’t run the risk of offending anybody.
Don’t laugh but my friend who is very much a hardcore atheist used “God dammit” and “Jesus fucking Christ” until that episode ran. Now its always “science dammit” and “fuck my monkey ass”. He means it (uses them seriously to swear) and it cracks me up every time.
That’s what confused me. It is precisely because I’m religious that I avoid profanity, but have relaxed a bit on vulgarity. The closest I get is using the word hell, but that’s specifically because I don’t consider it profane to use a bad place as a swear.
I’m surprised there aren’t New Yorkers out there that swear by using “New Jersey.”
I have a few phrases I’m fond of when the occasion arises:
- Jesus Christ on a popscicle stick (not even sure where this came from)
- Holy sheep shit!
- Sweet Sister Sadie (stolen from an old lover)
- Holy mother of god, Holy St Patrick, Jesus, Mary and Joseph (from Mom)
- Cocksucking motherfucker (usually when I’ve been drinking)
I tend towards Yosemite Sam-type cussing or geeky expletives most of the time though. When my guys at work hear me curse, it’s rare enough that it grabs their attention (and no, I don’t curse at them).
