A bit. Liberals need to fight harder for issues like subsidizing surrogate mothers for gay couples and allowing same-sex couples to adopt children.
Government paying mothers to give their children to someone else is a perfect example of neglecting the importance of family. Privileging funding for child care outside the home over supporting parents in caring for children at home is a less extreme example of this.
Creating families is a perfect example of neglecting the importance of family?
Monetizing parenthood into a commercial exchange can be an example of neglecting it's importance, yes, just as prostitution neglects the true importance of sexuality.
This metaphor only makes sense if you consider biological parenthood a necessity to be a person in the family. This should obviously be the most critical item on the agenda.
Anyway, liberal policies far from ignore the importance of families and really look to entirely benefit them in a way no Republican can. Anything said to the contrary is racialized rhetoric. Even college loan policies play an obvious role in family values in that it is hard if not impossible to start a family with that cloud hanging over you! And that's before we even get into SNAP funding and all the other necessities that Republicans wish to do away with to literally starve underclass families out.
