I was watching Germaine Greer and the phrase suddenly acquired a new effect on me. I've always just thought
"daft", but I suddenly realised it had an intention. As it is repeated it eliminates the woman who nourishes the child she bears. I had also been reading Greek myths. Apollo defended Orestes because mothers contribute nothing to babies, it all comes from the father. And Jason taunted Medea that she gave nothing to his sons. We could be headed, quite deliberately, back to Ancient Athens.
