Antireligion is opposition to religion. Antireligion is distinct from atheism (the absence of a belief in deities) and antitheism (an opposition to belief in deities), although antireligionists may be atheists or antitheists. The term may be used to describe opposition to organized religion, or to describe a broader opposition to any form of belief in the supernatural or the divine.
According to historian Michael Burleigh, antireligion found its first mass expression in revolutionary France in response to organised resistance to "organised ... irreligion...an 'anti-clerical' and self-styled 'non-religious' state."
The Soviet Union directed antireligious campaigns at all faiths, including Christian, Islamic, Buddhist and Shamanist religions. In the 1930s, during the Stalinist period, the government destroyed church buildings or put them into secular use (as museums of religion and atheism, clubs or storage facilities), executed clergy, prohibited the publication of most religious material and persecuted some members of religious groups. Less violent attempts to reduce or eliminate the influence of religion in society were also carried out at other times in Soviet history. For instance, it was usually necessary to be an atheist in order to acquire any important political position or any prestigious scientific job; thus many people became atheists in order to advance their careers. Different sources disagree on the results of all this, with some claiming the death of 21 million RussianOrthodox Christians by the Soviet government, not including other religious groups or persecutions without killings, and other sources stating that only up to 500,000 RussianOrthodox Christians were persecuted by the Soviet government, not including other religious groups.
The atheist state of the People's Republic of Albania had an objective for the eventual destruction of all religion in Albania, including a constitutional ban on religious activity and propaganda. The government nationalised most property of religious institutions and used it for non-religious purposes. Religious literature was banned. Many clergy and theists were tried, tortured, and executed. All foreign Roman Catholic clergy were expelled in 1946. Albania was the only country that ever officially banned religion.
The Khmer Rouge attempted to eliminate Cambodia's cultural heritage, including its religions. In the process, its acolytes killed nearly 1.7 million people.
Vladimir Lenin, who, like most Marxists, believed all religions to be "the organs of bourgeois reaction, used for the protection of the exploitation and the stupefaction of the working class"
Bill Maher, who wrote and starred in Religulous, a 2008 documentary criticizing and mocking religion.
Karl Marx, founder of Marxistcommunism, who wrote, "Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people".
Thomas Paine, English-American author and deist who wrote a scathing critique on religion in the The Age of Reason (1793-4). "All national institutions of churches, whether Jewish, Christian, or Turkish, appear to me no other than human inventions set up to terrify and enslave mankind, and monopolize power and profit".

^Many of us saw religion as harmless nonsense. Beliefs might lack all supporting evidence but, we thought, if people needed a crutch for consolation, where's the harm? September 11th changed all that. Revealed faith is not harmless nonsense, it can be lethally dangerous nonsense. Dangerous because it gives people unshakeable confidence in their own righteousness. Dangerous because it gives them false courage to kill themselves, which automatically removes normal barriers to killing others. Dangerous because it teaches enmity to others labelled only by a difference of inherited tradition. And dangerous because we have all bought into a weird respect, which uniquely protects religion from normal criticism. Let's now stop being so damned respectful!

^"Dewey felt that science alone contributed to 'human good,' which he defined exclusively in naturalistic terms. He rejected religion and metaphysics as valid supports for moral and social values, and felt that success of the scientific method presupposed the destruction of old knowledge before the new could be created. ...

^"[T]he Bible, contrary to what a majority of Americans apparently believe, is far from a source of higher moral values. Religions have given us stonings, witch-burnings, crusades, inquisitions, jihads, fatwas, suicide bombers, gay-bashers, abortion-clinic gunmen, and mothers who drown their sons so they can happily be united in heaven."

^"I think all the great religions of the world – Buddhism, Hinduism, Christianity, Islam and Communism – both untrue and harmful. It is evident as a matter of logic that, since they disagree, not more than one of them can be true. ... I am as firmly convinced that religions do harm as I am that they are untrue." Bertrand Russell in "My Religious Reminiscences" (1957), reprinted in The Basic Writings of Bertrand Russell
