Im Aussie and the words damn and hell arent swear words.
Also R rated movies in Seppo Ville are only rated M15+ here in Oz.
To tell someone you are "pissed" or "piss off" is swearing to me.
Im a huge Simpsons fan and a missionary couple looked down on me for admitting that, then in the following sentence the Elder used the word geez. To me thats offensive.
I think that if you cant say it in front of your mum, children, bishop, the prophet or heavenly father, then it must be wrong.
But definately doesnt reflect on the strength of your testimony IMHO:D
