I agree. This is garbage and doesn't belong in an encyclopaedic article, at least not without removing the obvious feminist bias. The "missing sun motif" section also states that Demeter is implied to be a sun goddess who departs in despair when her daughter is kidnapped, resulting in winter. Whoever wrote this has no idea what the myth is actually about. Demeter is the fertility of the earth, not the sun, and winter results from her neglecting her duty to bring forth nourishing crops during Persephone's absence. This story is told in the Homeric Hymn to Demeter.
