I agree with the thought of it ("I would love to have the word "catty" removed from any discussion of female authors from now on"). However, saying "we" use it to "describe women who aren't acting like sugar, spice, and everything nice" is a generalization on her part, not unlike some LKH has made.

I've read one of JA's books and didn't like it enough to continue, but on the whole, I respect her views on writing.
