The Pew Forum on Religion & Public Life has been studying the steady rise of hostility towards religious expression and religious liberty worldwide. In fact, they found that restrictions on religion rose in every major area of the world, including the United States, since the study began in 2009.
Citing what the Pew Forum calls “social hostilities” (as opposed to government hostilities), the study found that Pakistan, India and Iraq were the most hostile countries to religious freedom.
The Social Hostilities Index (SHI) measures acts of religious hostility by private individuals, organizations and social groups. This includes mob or sectarian violence, harassment over attire for religious reasons and other religion-related intimidation or abuse.
