Back when I went to school with mostly non-denominational protestants, I used to get in trouble for saying “rats”. We were taught that tossing
any interjection into a sentence was sinful, apart from maybe “oh”, “wow”, and placeholders like “um”. The same held true of adjectives with negative (or no) meaning. Kids would regularly get in trouble for using the words “stupid”, “dumb”, “hate”, or “goodness”, among other things. Other parents would ridicule mine for using the occasional “shoot”. I rebelled a bit in third grade and began saying “what the mad cow disease are you talking about” at every opportunity, as mad cow disease was the most random thing I could think of. It never caught on, though.
So yeah, when I stepped outside that realm (and particularly when I started using the internet), I was
appalled at the sorts of words that were bandied about. Nowadays, I don’t really mind it, provided it doesn’t interfere with basic sentence structure and isn’t used to insult individuals or groups of people. Quite honestly, I rather like being able to use the word cr*ppy to describe situations. I don’t do it terribly frequently, so I think it’s a fairly good way of making the extremeness of my opinion clear. I’ve occasionally used the word b—s—, although the instances could be counted on my fingers. I only use it for cases of
extremely strong feeling that something or other is a harmful falsehood. Or once when I was playing a card game involving bluffing. Once.
I’ve even come to appreciate the much harder vulgarities that I would never personally use. They allow us to make it clear that the anger, frustration, and pain we are feeling are extreme. I believe that part of the reason that my school banned all replacement expletives is that it was banning negative feelings, attempting to require us to be happy. When you can’t say that you “hate” something, and are required to say that you “strongly dislike” it, it comes off as an attempt to invalidate your feelings and experiences. When circumstances are making us extremely unhappy, I think it’s acceptable to use words to express that emotion. I also think that it can be acceptable to use vulgarities as verbal shorthand for those feelings.
I would be interested in seeing any document that says otherwise- particularly one that explains how we would distinguish between truly “bad” words, such as the two censored ones above, and the harmless ones that the CAF censor does not block.
I do think that we should only use our words for constructive purposes. While using a vulgar word to convey extreme emotional pain could be constructive, cussing someone out wouldn’t be. I’ve always been pretty sure that using such words to attack or insult people is a sin (Shakespeare notwithstanding). I also do get annoyed when people use such words to convey something other than extreme emotion, and I do make an effort not to use any sort of vulgarity (including things that even I consider tame) around people who may be offended, since I want people to be comfortable around me. But even so, I’ve come to think that colorful metaphors have their uses.
So cussing is considered as a vice or bad habit like smoking but I don’t think someone would go to hell for cussing alone. If they were holy in every way but said a cuss word just before getting hit and killed I don’t think that one cuss word would condemn them to hell. I would hope they would call on Jesus, but if a bad word came out I don’t see them going to hell for that.
– those just aren’t the words that are on the tip of my tongue. You’re looking at the guy who, in his high school English class, switched in the word “donkey” for that other word when reading Shakespeare in front of the class.
