For what it's worth, I object to hearing people talk about their "natural" birth that involved an epidural, and forceps. I wouldn't really refer to that as a "natural" birth either...
I agree! I am fine with people using the term 'natural birth' if in fact it was a drug free birth. I do not like it when people say they had a natural birth which involved an epidural and forceps (as Michael pointed out), to me that is a 'vaginal birth'.

When I am asked how I will be birthing this baby (after a CS with DD) I say I am aiming for a vaginal birth and to have a natural birth would be an added bonus .

I am lucky I suppose that I have not had any negative comments towards having a CS, I think because DD was born very sick they realised that the outcome may have been very different (possibly alot worse that is) if she was born vaginally. Although I do still hate having to say that I had a CS and avoid it if I can, I am hoping that this time I can have a vaginal birth, I might then be able to the negatives of a CS behind me.
