The books are cute. I've read them to my preschoolers several times. I don't care that she is the person who wrote them (or didn't write them, whichever you believe) I care about the words on the page.
I will share a similar story. When I worked at a bookstore a few years back, we always had several of the current CD's randomly playing. I was checking a woman out when one of Madonna's songs that was popular at the time (don't remember which one) and she was tapping along and said she really liked the song playing, did I know who sang it. I told her it was Madonna and literally in less than a second, her expression changed. "Oh, well, I guess it isn't that good then, is it?" I responded (and I shouldn't have, and got talked to later about it-- although with a smile from my supervisor) "Well, it was good two seconds ago, wasn't it?"
