Things I am super libertarian on: 1. Free expression - borderline absolutist, very narrow definition of hate speech/emergency measures possibly justifiable. 2. Freedom of conscience/religion. 3. State should not interfere in sexy times between consenting adults.
These are negative rights from the state - not guarantees that there aren't other consequences! As a corollary to number 3, I would say that I think porn is Mostly Bad, but that I think it's a problem that should be solved by tech/markets/civil society, not the state.
