What is meant by unchastity is the taint in a woman?

Dhammapada 242 and AN 8.15 say: > *Malitthiyā duccaritaṃ / malaṃ itthiyā duccaritaṃ* This is translated as: > *Unchastity is the taint in a woman. (Buddharakkhita)* > > *In a woman, misconduct is an impurity. (Thanissaro)* > > *Misconduct is a woman’s stain. (Sujato)* > > *A woman’s stain is misconduct. (Bodhi)* The above stain specific to women is found among other stains, as follows: > *Bhikkhus, there are these eight stains. What eight?* > > *(1) Non-recitation is the stain of the hymns.* > > *(2) The stain of houses is lack of upkeep.* > > *(3) The stain of beauty is laziness.* > > *(4) Heedlessness is the stain of a guard.* > > *(5) A woman’s stain is misconduct.* > > *(6) Miserliness is a donor’s stain.* > > *(7) Bad unwholesome qualities are stains in this world and the next.* > > *(8) A stain graver than this is ignorance, the very worst of stains.* > > *These, bhikkhus, are the eight stains.* Despite this focus on women above, the definition of sexual misconduct in the suttas is addressed to men, as follows: > *He engages in sensual misconduct. He gets sexually involved with those who are protected by their mothers, their fathers, their > brothers, their sisters, their relatives, or their Dhamma; those with > husbands, those who entail punishments, or even those crowned with > flowers by another man.* > >*AN 10.176* My question is why do Dhammapada 242 and AN 8.15 focus on sexual misconduct as the stain of a woman (when they are so many other stains, such as listed in MN 7)?
