anencephalic

Of, pertaining to, or exhibiting anencephaly.

Stupid, brainless

If Rita Mae Brown were an exceptional writer, I might be more willing to give an ear to her pontificating […] But even as a pulp writer, Brown will have to treat lesbians as more than a bunch of anencephalic semi-literates who will sanctify her name forevermore. We have to have the guts to say, "Keep editing, Rita Mae; paper is cheap and we expect better!"

A person, especially a fetus or newborn, affected by anencephaly.
