It seemed to me that you were representing that he was adopting a libertarian approach, and, by the way, things are going to hell, therefore, libertarianism is flawed. But he’s doing almost nothing that libertarians would do, so that argument isn’t a good one.
The thing that takes discernment is Obama's social idea's are exactly libertarian, but his economics are straight out of Marx. Ergo, people say he's a socialist/Marxist. All the economic libertarianism in the world, can't save a country that murders people in the name of freedom, or economics. If we are forced to keep ObamaCare, you will soon see it going broke and to conserve money, we will start withholding treatments and drugs to certain people that don't "deserve" the largess from the "real" needy people. Social libertarianism is the same thinking of economic liberalism. Economic theory from Milton Freedman and social theory from the Bible is what works. Social libertarianism will break down and require laws to regulate it,...it's inevitable. All the trans- bathrooms for children at school, Heather has 2 mommies, now they want multiple wives, children have 3 parents, and on and on, it's all from "What do you care as long as it doesn't affect you". Man's heart is continually evil, who can know it. Eventually, it will affect you.
Some libertarians invoke the Founders, as if they believe the Founders were on their side. The foundation of the country was on individual freedom and freedom to worship God. Atheists weren't elected or revered much in those days. The laws were ALL based on Scripture. The founders wanted people left alone until they sinned against God and nature. None were libertarian to my knowledge.
