Liberal is often a term used to describe any person who considers themself a strong proponent of a large and controlling government. They believe that powerful bureaucracies are needed in order to provide equality, personal safety and many other services such as health care. Their speech and actions convey emotional or popular opinion which is often used as a method of solving the perceived problems of society. Liberals also tend to admire popular or authoritarian figures such as dictators, movie stars, or anyone holding positions of power that are in line with a their own philosophy. Since the election of George W Bush in 2000 they have become overtly angry in their demeanor with anyone who disagrees with them while showing support for dictators such as Hugo Chavez (who recently nationalized many of the industries of Venezuela). Liberals openly use their collective positions of power within government to perpetuate their causes such as the current popular notion of a man made climate change. (Man Made Global Warming) Scientists who have openly disagreed with this premise have been threatened by the removal of their licenses or titles.
