No, libertarians by definition are not social conservatives, that is why they can’t just call themselves “conservative”, and real conservatives and Christians, are social conservative.
Libertarians are lefties who like conservative economics and are liberal on military and social issues, that is why Bill Maher and a lot of Hollywood lefties are proud to be libertarians.
I do call myself a libertarian and a social conservative which proves you wrong.
The definition of libertarian that most understand and I prefer is Merriam-Webster’s: “a person who upholds the principles of individual liberty especially of thought and action.”
As a libertarian and also a social conservative I’m in favor of a strong military and what some may call an interventionist foreign policy. For instance we should have taken out Castro 50 years ago. I’m in favor of private religious schools, prayer at public events and private contracts. I’m opposed to abortion, non-traditional marriage and government coercion.
Just where do you get the definition that “libertarians... are not social conservatives?” As a forty year reader of National Review I’m aware of many instances where William F. Buckley referred to himself as a “libertarian” and also a “social conservative.” Bill Maher (and most of the rest of the Hollywood crowd) on the other hand is a democrat half-wit that doesn’t understand the term any better than you do.
