Liberal is not interchangeable with libertarian. In this highlighted phrase, Thoreau (Civil Disobedience), the man thought to have first uttered this thought, was actually drawing upon the writings of a piece published (12 years earlier) in the first edition of "United States Magazine and Democratic Review." Given that today's' democrats are considered "liberals", and that Thoreau was an early democrat plagiarist of others' writings, I can see how someone might be confused and think this phrase is what liberals, rather than libertarians, believe. When its actually to the contrary. Liberals believe they know what is best for everybody and thereby require a strong, over reaching government, whose primary function is to silence and punish those who do not believe as liberals believe. Libertarians essentially want government to leave them alone.
That said, why worry about what a dying medium plans to do?
