I think the free sex and womens lib did more to upset the family than contraception did.
You don’t need drugs to help you. Women who have children with their abusers leave those same abusers every day. For many their children provide a motivation to escape that they did not have before. And, thanks to contraception, more and more dysfunctional relationships begin because contraceptive relationships are by definition lacking in authenticity.
But it is the contraception that created the opportunity to avoid the consequence of being promiscuous. It led to the idea of “free” sex.
Feminists are responsible for teaching women to desert their children and husbands, so those kids grow up to be emotional cripples and unable to form lasting relationships.
