I feel that. That's how it is in my area. People drop "F-bombs" in casual conversation all the time, like it's just a normal part of speaking. I guess I got into this habit as well so it takes conscious effort to try and not speak like a soldier.
and those are the times where I feel absolutely no conviction about it.
at those points it's just... words... they hold no power, and I'm not using them with evil intent.
only if I'm around friends that are Christian and have been raised to believe those words are inherently sinful, I avoid them around them, and it doesn't even take conscious effort.
it's just second nature "yeah these people consider these words bad" so instead of using a particular s word, I substitute "stuff" (which fits the context of the sentence where I'm using the vulgar word anyway), like "Yeah let me just go and grab my stuff" where around someone who curses like a sailor (and I was a sailor myself) it might not be the word "stuff"
but that doesn't make me feel like I've done some sin.
I generally wonder where this idea that vulgar terms are sinful even comes from biblically, one family I knew thought it was using the Lord's name in Vain, which, yeah, like I said, I HATE when people shout for God to condemn something when they're frustrated or just say the name of Jesus in a manner like profanity. I'd rather them use any dirty 4 letter word or bodily function or term for animals they wanted than profaning the Holy.
But I don't see how words for bodily functions or terms for animals is using the Lord's name in vain.
My Lord's name is not an animal, or any reference to any bodily function done on a toilet.
When Paul writes not to use any dirty talk, and then in another letter says
Philippians 3:8
Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ,
Modern day translation
"I lost everything, but compared to Jesus, they ain't ... stuff."
I think it's not the words that Paul means but how you use them, what is their intent? Are you trying to degrade someone? Offend someone? Are you using them to express hate or anger at someone? Are you wanting something bad to happen to someone when you use them? Are you using them to treat someone like a sex object rather than a sister in Christ?
There's the sin, and to me it doesn't matter what words you use to express it. Substitute "soft" curse words are every bit as convicting as "the real deal" when you use them in those contexts, aren't they?
Do you really believe that you have not sinned by using "darn" rather than "damn" when shouting "Darn you!" at someone you're angry with?
Your mouth may have said darn, but what was your heart saying?
But again, I won't use those words around people for whom they are stumbling blocks...
but, I think that last point was an important thing to consider, because the Lord weighs the heart.
