New Atheism is a movement that emerged in the early 21st century, characterized by a more outspoken and confrontational approach to atheism. Prominent figures include Richard Dawkins, Sam Harris, Daniel Dennett, and Christopher Hitchens, who argue against religious beliefs and advocate for science and reason. They often criticize organized religion for its influence on society and promote secularism. The movement gained traction through books, lectures, and debates, emphasizing the importance of questioning religious doctrines. New Atheists argue that faith can lead to harmful consequences, such as intolerance and violence, and they encourage a rational worldview based on evidence and critical thinking.
