Ivins describes herself as a Freethinker.
A contributor to the [message board] reports: "On C-SPAN the morning of Apr 15th 1999, Molly Ivins was the guest on Washington Journal. In an exchange with a caller concerning religion and abortion, she was asked about her religion and stated that she was a Christian.
In her November 24, 1999 syndicated column, Ivins discusses Wendy Kaminer's new book Sleeping with Extra-Terrestrials: The Rise of Irrationalism and Perils of Piety. Ivins talks about the book, mentioning pseudoscience, the recovered memory movement, criticizing religious leaders who seem to be above rebuke, ritual satanic abuse, etc.
Ivins then says: "I do think it would help if we had a public voice attacking the excesses of religion equivalent to the great 19th-century atheist Robert Ingersoll (who was once the Republican vice presidential candidate; try to think of a prominent atheist politician today)."
