Discrimination against atheists, sometimes called atheophobia, atheistophobia, or anti-atheism, both at present and historically, includes persecution of and discrimination against people who are identified as atheists. Discrimination against atheists may be manifested by negative attitudes, prejudice, hostility, hatred, fear, or intolerance towards atheists and atheism or even the complete denial of atheists existence. It is often expressed in distrust regardless of its manifestation. The main mechanism behind anti-atheist prejudice is the projection of believers' repressed desires. Perceived atheist prevalence seems to be correlated with reduction in prejudice. In some Muslim-majority countries, atheists face persecution and severe penalties such as the withdrawal of legal status or, in the case of apostasy, capital punishment. Because atheism can be defined in various ways, those discriminated against or persecuted on the grounds of being atheists might not have been considered atheists in a different time or place. Thirteen Muslim countries officially punish atheism or apostasy by death and Humanists International asserts that "the overwhelming majority" of the 193 member states of the United Nations "at best discriminate against citizens who have no belief in a god and at worst can jail them for offences dubbed blasphemy". Tim Whitmarsh argues atheism existed in the ancient world, though it remains difficult to assess its extent given that atheists are referenced (usually disparagingly) rather than having surviving writings. Given monotheism at the time was a minority view, atheism generally attacked polytheistic beliefs and associated practices in references found. The word "atheos" (godless) also was used for religious dissent generally (including the monotheists) which complicates study further. Despite these difficulties, Whitmarsh believes that otherwise atheism then was much the same. While atheists (or people perceived as such) were occasionally persecuted, this was rare (perhaps due to being a small group, plus a relative tolerance toward different religious views).
