Islamophobia, also referred to as anti-Muslim or anti-Islamic sentiment, is the irrational fear of, hostility towards, or hatred of the religion of Islam or Muslims in general. Islamophobia is characterised as a form of religious or cultural bigotry in which Muslims are stereotyped as a geopolitical threat or a source of terrorism. Muslims, with diverse ethnic and cultural backgrounds on a worldwide scale, are often inaccurately portrayed by Islamophobes as a single homogeneous racial group. The causes of increased Islamophobia across the world since the end of the Cold War are many. These include the quasi-racialist stereotypes against Muslims that proliferated through the Western media since the 1990s, the "war on terror" campaign launched by the United States after the September 11 attacks, the rise of the Islamic State in the aftermath of the Iraq War, terrorist attacks carried out by Islamist militants in the United States and Europe, anti-Muslim rhetoric disseminated by white nationalist organizations through the internet, and the radicalisation of Christian nationalist and far-right groups with growing hostility towards Muslims in the United States and the European Union. A study conducted in 2013 revealed that Muslim women, especially those wearing headscarves or face veils, are more vulnerable to suffer from Islamophobic attacks than Muslim men. Due to the racialised nature of Islamophobic discrimination and attacks suffered by numerous Muslims in their daily lives, several scholars have asserted that Islamophobia has explicit racist dimensions. On 15 March 2022, the United Nations General Assembly adopted a resolution by consensus which was introduced by Pakistan on behalf of the Organisation of Islamic Cooperation that proclaimed March 15 as 'International Day To Combat Islamophobia'. The exact definition of the term "Islamophobia" has been a subject of debate amongst Western analysts. Detractors of the term have proposed alternative terms, such as "anti-Muslim", to denote prejudice or discrimination against Muslims. It has been alleged, often by right-wing commentators, that the term is sometimes used to avoid criticism of Islam, by removing the distinction between racism and criticism of religious doctrine or practice. However, academics, activists and experts who support the terminology have denounced such characterisations as attempts to deny the existence of Islamophobia.
