To the contrary, ask a libertarian if they want more laws proscribing what were lawful activities, e.g. tobacco smoking, etc.?
Aaaa, you missed my point. I am certainly not saying that libertarians (large or small L) want more government involvement in personal choices.
What I'm saying is that the phrase "socially liberal" doesn't mean less government involvement in personal choices, but more government involvement in personal choices, just not the ones associated with the right.
For instance, a social liberal has no trouble supporting tobacco restrictions or trans-fat bans, but might support 'gay rights.' A libertarian would oppose tobacco/food nanny-statism and would realize that 'gay rights' are about being more equal, in the Orwellian sense.
The old classical meaning of liberalism is, unfortunately, quite dead, and only comes out of its grave to attempt to trick people into voting for Dem statists.
