Response: Every law known to man restricts "personal liberty," and in that sense is "against personal liberty." In most instances Libertarianism means Libertine-ism. The isolated individual floating in the void with relation to any other person, place or thing. Solipsism comes to mind.

I am not against laws. Laws are one of the things that allow mankind to exist in a, somewhat, orderly manner.
Sweeping laws that affect everyone, whether the action will hurt anyone besides the actor, are another thing altogether.
