A previous poster spelled it out:
> by encouraging and aggrandizing stable two-parent families instead of getting schools and teachers to fill proxy parenting roles
You seem to be thinking of "pushing back" as some sort of attack upon single parents, when I believe that the original spirit of the comment was more along the lines of:
Let's strive to spread awareness of the myriad of benefits two parents can provide in a child's life.
Let's try to move the conversation an inch or two away from 'my happiness above all else' and slightly more towards 'sometimes being part of a family requires sacrifice.'
Hell, let's create a national holiday dedicated to households with two parents raising children together as a team.
Let's remind people that they aren't freaks for not getting divorced as soon as the initial spark died down. That it's okay to continue trying to make things work for the benefit of their children.
So often today I encounter the sentiment that "there are so many fish in the sea, and it's so easy to find them, why bother putting effort into it if it isn't perfect from the get go?"
In my opinion, the prevalence of this school of thought is harmful to the propagation and stability of two parent families. American society at some point became so obsessed with "self care" that, you guessed it - they forgot about the children.
