Asked the question on Mind Meld:

Once upon a time, sf/f was full of taboos: no swearing, no sex, etc. We’re thankfully past those days, but are there any taboos still remaining or new ones that have sprung up? Have you ever had trouble with publishing something, or caught yourself self-censoring?

I found myself at a bit of a loss but, came up with this answer:

Well, every writer has had trouble getting stuff published, but probably because they breached the publishing world taboo of writing crap. For me, beyond 2000 when I was taken on by Macmillan, I’ve been censored all the time in that respect – it’s called editing. But no, I don’t really have much trouble getting stuff published and I don’t self censor … except all the time in regard to that first publishing taboo. Doubtless, in years to come some minority group lobby will run out of larger targets and focus its attention on SF books, and then violence, drinking, smoking and excessive consumption of beefburgers will be a no no. I just hope I’m in a position to give them the finger by then.

Other writers and those commenting have produced other answers over here. Some people might even find all this interesting. I have to add that I do self censor here — in fact I did it in the last sentence.
