Semantics and euphamism intended to hide the fact that abortion is murder. If you've read her non-fiction works, then it would be quite clear that she was very pro-abortion.
Who in their right mind would WANT to have an abortion, if they could avoid it?
Apparently there are quite a large number of women who WANT to have abortions. After all, nobody is dragging them into the clinics to have their children ripped out of the womb.
To my knowledge, she never had an abortion.
As I said, it is mere speculation on my part.
(If she had, I'm sure one of her critics would have brought it out by now.) During her child-bearing years, abortions were illegal and quite dangerous. I imagine she did what other intelligent women did -- use birth control.
Using birth control is certainly preferable to child murder.
