Fiscal conservative/social liberal.
Wrong.
For starters, "fiscal conservative" is a meaningless phrase. Paul Ryan is a fiscal conservative, and remember his budget didn't even balance for decades and it increased government spending. That is in no way libertarian whatsoever. As far as social liberal goes, libertarians, despite what Gary Johnson says, are not interested in using the government to create a fictitious "even playing ground." Libertarians want the government to leave people and their property alone.
"The fact is that libertarianism is not and does not pretend to be a complete moral or aesthetic theory; it is only a political theory, that is, the important subset of moral theory that deals with the proper role of violence in social life. Political theory deals with what is proper or improper for government to do, and government is distinguished from every other group in society as being the institution of organized violence. Libertarianism holds that the only proper role of violence is to defend person and property against violence, that any use of violence that goes beyond such just defense is itself aggressive, unjust, and criminal. Libertarianism, therefore, is a theory which states that everyone should be free of violent invasion, should he free to do as he sees fit except invade the person or property of another. What a person does with his or her life is vital and important, but is simply irrelevant to libertarianism." - Murray Rothbard
