your question almost warrants a PhD in applied linguistics ... i wonder How perversive other Religions are. You should read Asterix & Obelix. The authors transposed these Religions reference to the Roman religio-linguistic background replacing all references.

I use:
"Jesus Christ," as an expression of frustration or surprise
"God damn it"
"Oh my God" or "Holy shit," as an expression of surprise

Is "Dammit" actually a religious term? It doesn't seem like it has any religious connotation to it.

I tried for a while to exorcise them from my vocabulary, but it was too much. They're simply too ingrained in me as exclamations. But I have tried to switch to "Salut!" when people sneeze. I'm not trying to bless anybody, even in German.

Been using Jesus Christ in frustration or surprise for about 55 years, mimicked from my parents (Jewish)

Been using Jesus Fucking Christ more and more as my health worsens, must be his fault right?

Not sure why damnit is religious (because only religious people can be damned????) But also have used that for about 55 years

But their argument makes about as much sense as saying if you use the word Kibbitz you must be Jewish. If you say "voila!" you must be French etc.

I like the Jesus fucking Christ, unfortunately I rarely have the opportunity to use it.

I also use “amen” as a confirmation. I do try to replace those sayings with others, but it has been in grained in me since I was a child. It’s a habit, not religious.

My ex wife used to say "Oh my god oh my god oh my god" as she orgasmed, I thought she meant me.

I do not use any of those terms.

Not so much anymore. I used to . One I use often is Holy Houdini. Lol

Habits are slow to die. One I do use a lot is "good lord."

God damnt to fucking holy hell no, never.

I use thoughts and prayers to rile people up. Does that count?

Jesus Fucking Christ is a favorite.
As is holy shit.

I say a lot of religious phrases despite not believing.

"Oh god" "for God's sake" "Jesus christ"

But I've always said gesundheit instead of bless you

I use Holy Shit a lot.

Seriously, words are words. When/if I do say them, it's out of habit.

I do use "thank the Gods" just to piss of Christians since they insist there is only one true God.

My dad cussed whenever he worked on a car. As I had kids, i realised I was apt to do the same thing so I created my own curse word to call cantankerous pieces of machines. Ubiquitous Whore. I found saying that at inanimate objects helped keep me from using any reference to god.

I didn't really use those expressions when I was religious. I make it a point not to use them now, but due slip out on ocassion. For some people it's force of habit and not implying religious bs.

Jesus tap dancing Christ yes!

Having been brought up Catholic and had cousins and uncles who were nuns or priests, I was told that "damn" is derived from God damn and is just as bad because when saying it you arr invoking or inciting God to send someone or something to Hell to suffer eternal damnation.
And remember, I'm just the messenger, and I'm signed up on this site too...

I was raised in a religious household and yes those phrases were used a lot, they are engrained in my reactive response vocabulary. I've only been atheist for about a year now and every now and then I catch myself and try to switch phrases out with something that doesn't have anything to do with "God" or "Jesus".

I've gotten good at omitting "God" in front of "dammit", cutting the reactive exclamation "Jesus Christ" down to "geez", and switching a lot out for "fuck".

I am a life-long non-believer in anything having o do with the supernatural or paranormal. Very early in my life (I was born in 1944 so it has been a while) I argued with cousins about Santa Claus. My logic was simple. I knew reindeer didn't fly and felt that fact alone discredited the whole program from square one.

Being born in North Carolina it was normal to pick up utterances such as Heaven knows or Thank god for or that and a rash of such simpleton horse manure. I was a skeptic even before I knew the word or concept, and when I did I thought, "that's what i am" and adopted both immediately. It wasn't long before I also adopted agnostic and eventually that morphed to atheist.

I tell people I'm a "card-carrying atheist" and then hand them my calling card that has "ATHEOS" under my name, with my cell # and address. I lead two atheist Meet Up sites and meet with fellow atheists every Sunday afternoon. Denton Atheist and Wise Free Thinkers and Skeptics; do a search for the terms.

When I came out as an atheist some 40-years ago, I decided then it was ridiculous to have such phrases in my vocabulary and began a private effort to rid myself of that trash and I'm pleased to report I was successful.

Also a question if I may; When you make a new friend whom you think is smart, intelligent or sharp are you disappointed to learn that are religious? I am.

I don't avoid religious speak. Its nothing more than colloquial vernacular with nothing reverental involved. I will say, " my hand to Jesus/heaven/god" but I also say things like "Jesus fuck" "jumping jesus on a pgo stick", etc.

I use Jesus Christ, but you have to say it like this:

I use “god damn it” and “god fucking damn it” quite often. I also use “aww hell” and “hell yeah” a lot.
