Thats possibly the dumbest and most irresponsible thing ive read all week. Children need two caretakers of ideally different genders, or otherwise role models actively involved in their development to compensate, to develop into truly well rounded and emotionally stable and healthy people. That is a proven fact.
The nucleus family model evidently achieves better results than any variant of single parenting, simply because there are two caretakers instead of one. You make it sound like in vitro fertilization of single women is some sort of yass queen feminist shortcut to having a well adjusted child, it definitely is not.
And a woman in that situation should seriously ask herself if a deliberately fatherless child in their life is actually for that not yet existing kid, or an act of vanity and inability to emotionally connect to a potential father.
How so? Would you actually argue that the time and resources of two people are not more effective than those of just one? Or that any child needs both male and female role models and people of trust in their lives?
