A libertarian is someone who believes in maximizing individual freedom and minimizing government intervention in people's lives. They advocate for personal responsibility and the idea that individuals should have the right to make their own choices, as long as those choices do not harm others. This philosophy often extends to areas like free markets, civil liberties, and personal privacy. Libertarians typically oppose excessive regulations and taxes, arguing that these limit personal freedoms. They support a limited government that focuses on protecting individual rights rather than controlling people's actions. This belief system can be seen in various political movements and organizations, such as the Libertarian Party.
