From the progressive perspective a woman has that choice because she is a fully empowered individual. Thus we have been accused of supporting '60s values and strange family arrangements such as free love communes and polygamous groups. Of course this is foolishness as most progressives are in couple-based families. Many of us are in families with only one parent, and some are in others where the couple consists of mixed ethnicity or same- sex partners. These are legitimate families, which we should honor and defend.
Conservatives extol the traditional view of the family because it is what they know.
To move away from it is profoundly unsettling. More than giving up power, it requires them to restructure their view of themselves and the world. But it also raises uncomfortable questions about the U.S. worldview and the wisdom of our role as the world police force. Because conservatives view everything through the lens of patriarchy, they see the world as inherently dangerous where it is a unique role of men to defend the home and the country. This requires guns in the home and a huge military in the country.
