The growing presence of atheism in the United States continues to bring up difficult questions about the role of religion and the existence of God and has led to a surge in Christian apologetics. The 21st-century "new atheists," including bloggers and authors such as Sam Harris, Richard Dawkins, Christopher Hitchens, and Daniel Dennett, affirm their beliefs more openly and publicly than ever before. Recognizing the value of community living presented by religious groups, atheists and other non-theists have even founded church-like community groups and summer camps, though the range of atheist opinions on dialoguing with religious institutions varies widely. Christianity Today continues to analyze and track the influence of atheism and secularism on politics, society, and popular thought.
