Indeed, we live in a culture where swearing has evolved into a major linguistic pattern, I think many of us are accustomed to the 'facile' nature of using swear words left right and centre instead of a more interesting vocabulary. I swear A LOT, whenever I'm visiting my agnostic/atheist mother, she finds my obsession with swearing annoying. And often requests that I cut it out. I don't think she is 'right' or 'wrong' about her request. But my mother has always lived outside pop culture, whereas I've been a partaker of pop-culture and many of the hedonistic pleasures it involves.
I've often discussed the linguistic patterns of swearing before in a strictly cultural sense, but this discussion of swearing's linguistic value to atheists is an interesting and novel topic, on which I'll do some additional pondering... :)
I've always found that food products make good swear words, and they get noticed more. One of my favorites is "cheese nibbles."
My favorite swear phrase also involves food and was coined by Kurt Vonnegut. "Take a flying fuck at a rolling doughnut."
If I want to cuss something scandalous around religious people, I usually say, "bloody Jesus on a stick!"
You reminded me of a swear that works better in croatin, but here it goes:
F*ck soup made from nails Jesus Christ was crucified with
Jesus H. Christ --> Jesus Fucking Christ
Jesus --> Fuck that Jesus dude.
BTW - this is a losing battle. The speech center that provides the wellspring of spontaneous epithets is not the same as the cognitive speech center. Read Steven Pinker instead of wishing in one hand and shitting in the other.
Just in respondse to the title:
I think that blaspheming against a religion is hardly advancing its cause. Almost any Christian would object to using "Jesus Christ" and "shit" in the same contexts. Blasphemy is, after all, expressly forbidden to its constituents. It seems almost like a kind of protest against religion, showing that we don't fear its power.
I've found its also fun to change it up and swear with different religions. It's easy to get around taboos that way.
I don't remember if it was from Dennet or Dawkins but an alternative for :
