Profanity And Science Fiction

Have you noticed that as of late, some SF novels and stories now include profanity? I have. I started reading and watching SF as a child in the 60's. It is true that some SF shows like StarTrek had its moments under the sun due to the times, but still a child could see it on prime time TV. I am sure most of us were interested in science as a kid. We built volcanoes, gadgets, etc. Where did we get our ideas?

Science fiction. Good, clean, enjoyable science fiction. You knew Flash Gordon had a thing for Dale, without a scene of him banging her under the sheets. The romance was there just by the way they looked and talked to each other. For a kid--well that's yucky anyway--- of course puberty sets in, and ...ahem... opinions change. However, many stories were still clean.

So far I  have read Singularity and  I am  also listening to Leviathan, and both have profanity. Singularity has a racey sex theme, which really has nothing to do with the story. In my personal opinion, it kills the genre. Take a look at 'Transformers: Rise of the Fallen'.

 Homo-sex among dogs? A deceptacon humping Megan Fox's leg? What has that to do with SF? To avoid the R rating, the dialogue goes with f'ing this or f'ing that. Even the 'Dune' Latest triology "imprinting" to  restore a Ghoula memories in most cases, or for an Honored Matre to control a male, some wild ferocious and perverted sex act as to be descripted. What does this have to do with SF?

Nothing, absolutle @#&^!!! Nothing!
I beg all ye' writers out there. Please, Please Keep SF, F'ing
clean.... Alright? Make it enjoyable so children can get interested in science fiction again.
