I'm amazed that the discussion has managed to remain civilized thus far. The topic of abortion pushes people's buttons in a way that few others do--specifically because it is a question of life and death, and the death of a complete innocent.
I'll chime in with most of the others on the side of freedom of speech, to say if you don't like it, don't read it. I do, however, think that abortion is not snuff, and should be identified as such. To have it spring out at you in something you are reading is a little disquieting.
And something to add--someone mentioned that Stephen King has used abortion in his novels, and I have to say that it's all in how that subject matter is handled. Stephen King makes it a horrible thing, a tool of terror, at least in every book of his I've ever read. This use was different, and if it was intended to be funny...well, it takes a talent above and beyond almost any I can imagine to make the death of an unborn child in any way humorous.
I'm trying very hard not to come down too judgemental. I haven't read the work, and I won't. I will just say that there should be something in either the story codes or the story summary to warn people browsing through the forums. Regardless of when you believe life starts, just as the author has the right to say what he'she likes, the reader has the option to choose what they read.
