Are QTIPs Sexist?

Back when I kept up with estate planning trends, Qualified Terminable Interest Property Trusts were attractive to well-to-do men and women with children from a prior marriage. With a QTIP, one could take advantage of the marital deduction yet assure that trust assets remaining at the death of the surviving spouse would pass to one's children, not to the spouse's children or other relatives.

Haven't read Wendy Gerzog's paper, but the abstract Gerry Beyer posts at Super-charged power-of-appointment trusts asserts that QTIPs are sexist. Is it true that married women never, or almost never, use QTIPs in their estate plans?
