Don't step over that line!

With horror writing abounding over in Zombie July, let's talk about our own writing limits.

What will you absolutely not write no matter what? Even if the story tends to lead toward it. And where do you put your foot down in your genre? Do you write fantasy but not darker than a medium shade of grey? Do you write erotica and rape is not acceptable to you? Let us know your reasons why!

I will write violence to a certain extent but not go into graphic detail about anything. Unless it's essential to the story I'd rather leave it before the violence starts with the hint that it's going to happen. I think that's pretty much my limit in any genre with any type of violence.

The reason is just that I don't really like writing extreme violence and I don't think I could do it justice anyway, so I'd rather go with the Blair Witch effect and hint at things rather than showing them. I think the reader's imagination is likely to come up with much more interesting things than anything I could put on paper in that respect.

Bonus: For fun, what genre will you never ever ever write?

Easy question - I will never write horror or erotica. I don't like reading them and I can't imagine ever wanting to write them either.
