errr actually it's much worse if they do believe in means as then they are not damn in what they are talking about they are breaking the law of god and disobeying him in taking his name in vain.
but again it should offend no Christian but only invoke a need to aid the other person.
yes your are correct.
it is much WORSE if they beleive what they say when they say it.
not more offensive to me though.
