If it affects at most a handful of people–or if it must be combined with the decisions of dozens or hundreds of others–then that system is Liberal.
I will note that this includes within it the tyrannical potential of direct Democracy of the Athenian or French Revolutionary sort, in which a group of people, but ONE body, has the power over life and death for anyone it chooses.
Within our system, there are many bodies–two houses of Congress, 3 branches of government, 50 state governments, countless local governments, and a system of law which by design restricts Federal control of any number of things, including gun ownership, criminal justice, and speech. There are firewalls to block the effect of a decision, in answer to which relative unity of view must prevail for large scale policies.
