Huh? Smoking does not violate anyone's rights ("secondhand smoke" threats have been thoroughly discredited), and as such libertarians oppose restrictions on smoking such as those imposed by the Republican mayor of New York.
OH but what about the pursuit of happiness?
Let’s look at the statement again.
A Libertarian believes in individual rights, so long as they don't infringe upon someone else's individual rights. Therefore the "limited Government" should only intervene when an individual's actions may cause another to lose his or her right to life, liberty and the pursuit of happiness.
I hate to be overly critical, but it is important to realize that the present so-called "Republican mayor" was a Demodog. He switched parties to avoid major competition in the demodog primary not long before that election. Why NYC "Republicans" voted for him in the Republican primary is a mystery to me, but he certainly was a better choice than the super-liberal the Demodogs ran in the general election.
