Create your pro-dope, pro-sodomy, pro-porn, anti-family Nirvana--your stinking sewer on a hill.Do you regard the United States as pro-blasphemy and pro-idolatry?
Those things are not only legal, they're Constitutional rights. And I don't mean like abortion or buggery. They actually are Constitutional rights, right there in the text.
They'll never be happy until they dictate everyone's behavior to their liking. But then they scream when the Democrats try to do that, too. They also will not learn that people are perfectly welcome to join private groups pushing for certain societal aims, changing minds and hearts about social behaviors. I am pro-life (and although I'm not a member, there is a group called "Libertarians for Life"), I don't do drugs nor do I believe in doing them (but the WOD does not reduce drug use, but merely gives the government an excuse to disregard the 4th amendment--just like Prohibition was crucial to the rise of organized crime, but didn't stop people from drinking), I am heterosexual (but frankly don't care what anyone does in their own bedroom). The point is they simply don't trust people with self-governance.
FWIW, I actually prefer the term "classical liberal" because it more accurately describes my beliefs, since I'm not a capital "L" Libertarian, but the small "l" variety.
