Reply #211: When I had chemotherapy, it killed the cancer cells in my body.

The statement that she decided to have the fetus killed is factually accurate (unless it was a miscarriage, as some have suggested).

The statement that this was an evil deed -- including an implication that it was morally on a par with murdering a human -- is an opinion.

A defamation action does not lie for a factual statement that is true or for the expression of an opinion.

It's likely, however, that she has a very good case for invasion of privacy (public disclosure of private facts). Indeed, I dimly recall that there's some authority that, to win on a claim that your privacy was invaded, you must show that the statement about you was true. Otherwise, it's not public disclosure of private facts.
