I'm against the separatism and isolationism that nuclear families promotes for women. Single parenthood is directly the result of encouraging complete dependency on another person especially on a sex that is not naturally inclined to be a parent.Are you just against the male led, top-down structure or 2 parent homes period?
If 2 parent households worked there wouldn't be so many laws and ideologies needed to keep them together. And even with all that they still fail the vast majority of the time.
That being said, it makes no sense to depend on someone who is naturally inclined to roam. Again these structures fail over and over and over again. The same arguements for it has been made for generations and its worse than its ever been.
Time to do what works. Not what makes one party feel good.
