Females don’t have to kill baby boys. Just not nurture them. Females are forced to *birth* baby boys, but beyond that a female’s physical actions are her own.
Males will die without the constant infusion of female energy that they get from our wombs and from our lives. They are perfectly welcome to take the male infants from the hands of the midwife, and what they do with it from that point is *their* decision.
Females need to not be emotionally and intellectually invested in a male future.
