Strange how discussion on this topic tends to revolve around the women's fertility, and not the men that play at least an equal part in the creation of an embryo (may be more responsible if there are rape/ coerced consent issues) and there are probably more men that are a hazard to society in this regard.
It's almost always women being sterilised. In some cases men and women but women are always there. Which is interesting because IM (extensive) E none of these women have babies in a vacuum. There is always abuse. Generally how it goes is... Girl born into a crap family with an abusive father/mum's boyfriend and neglectful mother. Girl is abused, sees her mother abused, if the man in the house is the mum's boyfriend she is often sexually abused. Sometimes if it's her father. She leaves, tries to heal, fails, gets addicted, meets a man just like she's used to. Tries to replace her shit birth family with her own, has a baby. Wants to believe she can heal her past but she has no skills and a shit man around. Man carries on abusing her, she carries on using, baby born addicted, cycle carries on.
The one thing which is almost always present is male violence. But it's female fertility that we consider.
In Canada there is a program where pregnant, addicted women are given housing, healthcare, counselling and care without an expectation of stopping use. Abusive partners cannot enter the housing and they do family/couples counselling if a supportive partner is present. What they found is that addicted mother's babies do better when the abuse, homelessness, lack of healthcare, sex work and violence stop than if you stop the drugs and leave all the abuse and neglect. Better outcomes and healthier babies.
But we don't do that. Because stopping male violence is just too difficult. So we leave women in these situations, let them become damaged by them and them when they try to heal themselves with families, blame them for it. Up to considering sterilisation for them rather than vasectomies for men like this.
I helped out in a program for vulnerable teenage mums once that had THREE young mums being abused and pregnant by the same father. He was horribly violent to these girls. And they were girls when he got involved with them. But yeah, sterilise the girls.
