Once upon a time I thought libertarianism was a good idea. Then I met some libertarians. Sheesh.
Conservatives rightly believe that, in the public interest, certain behaviors should be prohibited and policed in the public square.
The state and its police are in turn restricted by laws pertaining to privacy, probable cause, prior restraint, etc. IOW, people can still choose to engage in those activities—dope, prostitution, whatever—but they’ve got to keep it “in the closet”, behind closed doors, and away from other people’s children.
The left wants everything in your face, anything goes. Nobody is safe, nobody has any privacy, or any right to refuse participation.
I also used to think libertarianism was good. Then I read the LP party platform carefully over the years, and “debated” (if you can call it that) libertarians on FR.
Libertarianism is a utopian philosophy which cannot work in the real world, plus it is founded on utter selfish hedonism.
