There's certainly plenty of indication in her article titles and the venues in which they were published that she's propabably a secularist, but I honestly don't see where you make the jump to "leftist". Maybe she is or isn't, I just honestly don't see any political indications. (Excepting possibly the several articles relating to Sidney Hook who was indeed a "leftist," if also a strong anti-communist and widely respected by many classical liberals. However none of these articles seem to relate to Hook's political views.)
"Maybe she is or isn't, I just honestly don't see any political indications."
just ... wow.
