Why does government have a stake in this? Because it has a stake in encouraging the parents to provide a stable, loving, committed relationship as the morally best environment for raising children. Government has a stake in encouraging couples together to raise their children and to provide examples for their children of parental relationship. Children, after all, are the future of the state. They provide the foundation for society’s future success or failure, so government has an interest in encourage certain behaviors in relation to children and in discouraging others."
The entire article is a good read and Brumley gets more into the child-rearing aspect further on in it. One of the most important first steps in taking on Leftist bigots who enjoy stifling rational discussion through feel-goody, appeal-to-emotional rhetoric is to immediately take emotional arguments off the table and get down to verifiable, empirical evidence. Once that occurs the anti-free speecher is then diminished to the poorly informed, mindless lemming that they are. That doesn't necssarily mean that they are bad people, just that they swallowed hook-line-and-sinker a poorly thought out position based on emotionalism rather than actually thinking the issue through to it's logical conclusion.
