This is libertarian thinking at its worse. OF COURSE the federal government must be involved in social issues. Take marriage as a current and prime example. Marriage is not just a civil or religious concern, it is a concern vital and integral to national security. A healthy marriage is the foundation to a healthy society. Any county that wants to survive and thrive promotes and protects the family. Any country that wants to escalate into a fiscal, social and moral black-hole can follow America's example since we entered into the Great Society.
Social issues are the key to our survival as a nation. Nothing else comes close. Not a 16 trillion dollar debt. Not unemployment. Not nothing.
You are suggesting that government can enact legislation that will foster healthy marriages? I don’t see any evidence over the last 30 years to validate that claim. I’m all for healthy marriages but just how do you propose the government does that? My opinion is that is a role for the church not the state.
Then you have an obligation to amend the Constitution to permit the Federal government to get involved in those issues. If you want to undermine our country’s foundations, I know of no faster way than to violate or ignore the Constitution. It puts you in league with El Presidente.
Social issues are the key? Show me where the founders advocate as such? The founders deliberately stayed away from personal and social issues, including an official religion, understanding that a government with the authority to grant such powers would have the authority to take them away. The Founding Fathers did realize that a social issue is not something you build or in our case rebuild a country on. Until we all get that through our heads, we will doom the conservative cause.
So, in comes the argument that we are confronted with social issues that the Founders could not have imagined. True, and they were confronted with some that are beyond our comprehension (ie slavery). If we accept that argument, then we have to conclude that the founding documents of the Constitution and Declaration of Independence have to evolve over time - and liberals would thank you for that thinking.
