Now that I'm an atheist, I need some new vocabulary. "Oh my God!", "Good Lord!", Jesus Christ!", and "God damn it" all have to go. What can I replace these God-isms with except for Atheism-isms - but which ones? What else to say instead? There ought to be a hand-book or something... let's make one. And let's have fun (I hope) doing it.
The vocabulary you use is best adjusted according to the target audience.
First of all, I have to say that there is NO such thing as bad words . . . only bad intent.
Taking that into consideration, religious folk will not "get" or care about atheist substitutions for God, Jesus or anything else they hold holy. Atheists might enjoy it . . . but believers will be left in the dark, in general.
"God damn it" will hold more import than "FSM damn it". "For Christ's sake" will grab attention more than "Great Zeus".
Like it or not, most cultures around the world identify with an Abrahamic god. That's our history and that's the root of many cultures.
Shock values comes from challenging the accepted worldview. I can only hope that, one day, people will exclaim, "What in the name of Science are you talking about?!?"
In some ways I want them to be shocked! I want to take the name of thier lord in vain. The Christians will care less if I say "Vishnue fucking Vishnue". But other than breaking Victorian Rules of Conduct, who cares about cussing. Only a little more than 100 years ago was "Humbug" the same as "Bullshit". Now even bullshit isnt that big of a deal.
I say we take the name of thier god and shove down their God Damn Fucking Throats like they do to us all the time!
