No, this thread isn't in the Religion Forum. I'm also not saying that particular rules of the Religion Forum apply (or should apply) elsewhere. I do notice the presence of that rule over there, though, and think a bit about what the rule reflects.
More later about the rest of your post.
I find it fascinating that the word, “crap” is offensive to some people. I find it comical that you can talk about hell, but when you say something like, “what the hell”, the context suddenly makes the word “bad”.
I think it is thee spirit behind the use of the word that matters. So, is it worse to say damn than darn, or f**kin’ instead of frickin’? Or “rats” instead of “sh**”. The whole thing is a fascinating issue to me and I put it in this context:
IN the fifties, it was common to light up a cigarette at the dinner table, but no-one would EVER consider it appropriate to say the f word. And today, it’s common to hear the f word at the dinner table, but no-one would ever consider lighting up a cigarette.
i.e. it’s all cultural norms, which ebb and flow.
