The UN Declaration on Human Rights guarantees that every man and woman has:
the right to freedom of thought, conscience and religion; this right includes freedom to change his religion or belief, and freedom, either alone or in community with others and in public or private, to manifest his religion or belief in teaching, practice, worship and observance.
These words have not translated well into practice, at least according to a recent Pew study that shows religious freedom in retreat around the globe. It is not for lack of attention though. A multimillion-dollar NGO industry publishes countless reports on persecution, and civic leaders regularly express their concern. Still, religious minorities find the world less diverse and more dangerous every year.
