It's not libellous to say this:
[Anti Catholics for Choice is] an astroturf corporately-funded anti-Catholic group with next to no members, which tells lies about the Catholic Church's teachings on abortion, engages in witch hunts against Catholics in public life, has an adulterous population-controller as its in-house "theologian" and takes money from porn merchants.
I'm sure that Elfriede knows very well that she isn't a Catholic. She should stop telling public untruths and pretending that she is one.
Fact: The ultimate defence against a libel action is the truth.
