Getting back to the OP, I think the problem is that we don't have a clear consensus on the purpose of government. I do think many (most?) liberals see the government as paternalistic - that it's there to take care of us, guide us, monitor our decisions and overrule those decisions if the state thinks they are bad. In a democracy, this generally means forcing the will of the majority on everyone else.
Libertarians, and some conservatives, believe the government is there, first and foremost, to protect our freedom. It should protect our freedom to create the kind of society we want, rather than forcing us to conform to any one vision of the "good life".
