unmanliness/unmanly

see unmasculine for an explanation of the subjective cultural meanings involved here. Replace these limp terms with descriptive adjectives: dishonesty/dishonest, cowardice/cowardly, deviousness/crooked, weakness/weak, fearfulness/fearful, timidity/timid. These words can be applied equally well to a woman and are not synonyms for unmanliness/unmanly but simply the stereotypical and unreflected notions of a sexist society on what it means to be a man.
