Going waaaaaay way back in the thread here for just a moment...: I really like having the authors on here. Being able to interact with them was one of the big attractions for my coming out of lurkdom. And they have a unique insight into the world of Trek production; probably the closest most of us will ever get to being able to peer inside the franchise. Well, I guess Bob Orci posting over at TrekMovie counts in some way; and the Okudas do post here some. Still, though, the interactions with the authors on the TrekLit board are certainly the most extended interactions we get.
And, I mean, think about how cool this is. 40 years ago, hell, 20 years ago, what were your odds of being able to have an extended conversation with authors (plural!) of some of your favorite books? Pretty slim, I'd say. The wonders of the Internet age...
Now returning to your current thread, already in progress... (heads-up: I spell out most of my swears, so if that bothers you, be forewarned.)
I use f-bombs in conversation with people, though not at work, not at church, and not with people above a certain age. The use of the f-word doesn't bother me in particular, though I sometimes wonder if it was really necessary for someone to use it. I think Christopher mentioned this earlier, but it seems to me that young people are rapidly using up all of our profanity, leaving eviscerated swear words in our wake. You gotta save some words for really strong moments, and I think we're losing such words.
In my books:
"Damn" and "hell" are basically fine, unless you're around pre-teen kids. I would feel fine using these around most older people, although if I knew someone was particularly conservative, I might switch into my "gosh, golly, goodness" mode.
"Crap" is not a swear, although I wouldn't use it around my grandmother. "Sucks," for idiosyncratic reasons, is a swear, but a very mild one; though it is not strong, it is kinda crass, and I'd use it liberally in some circles and not at all in others. "Ass" is like "sucks," but a fair bit stronger; again, it's kinda crass, which can be fine quite a bit of the time.
"Shit" is a swear. I think it's more acceptable to use it as a curse, as in, *drop hammer on foot* "Shit!", than as in, "This truck is a piece of shit." On the other hand, I will sometimes use it in the second sense to remind people I'm with that we're not all from high society.
"Bastard" doesn't bother me. I almost think I would be okay using it with my kids when I eventually have them. You know, starting around age 8. Obviously, standards will be different then, but that describes what I think is appropriate now.
"Bitch" is a strong word, and I would be angry if it were used to describe someone I care about. I rarely have cause to use it myself, but I would not be uncomfortable doing so.
"Dick" is a bit like a male equivalent for "bitch," in my books, but (not surprisingly) not as strong. "Douche(bag)" may be a better equivalent; I feel a lot less comfortable using it.
I hate the c-word, both when used to refer to female genitalia and when used to refer to a person. Again, this is idiosyncratic, but I find it very vulgar; any occasion I might have to use it, I would stop myself and say "bitch" or "asshole" instead. The c-word just seems too misogynistic to me, based on my experience with it. (Not saying that everyone who uses it hates women!! Just that it has too many associations for me.) Not a big fan of "pussy" either, tbh.
In terms of swears in TrekLit, I'm basically good with where stuff is now. (Where it's okay to say "damn, hell, shit, ass(hole), bitch and bastard".) The one thing for me, though, is I would find certain situations more believable if an f-bomb was dropped occasionally. Leybenzon, I'm looking at you: I really find it hard to believe that the folks on the frontlines during the War(s) would not use an occasional "fuck".
It's really interesting, though, to see how non-universal profanity is. I remember my dad telling me about his father, who was born at the beginning of the twentieth century and who lived his entire life in the middle of nowhere Oklahoma. Worked shit jobs his whole life because he was blackballed for organizing during the 20's and 30's. Cottonseed oil mills and the like. Built the family home with his own two hands, too. My dad's family was poor as dirt and they knew it. But my grandfather never cussed. Might've said "crap" once in a while. But that was it. The man had a thousand reasons to swear but never did.
Times change.
