Principle 21:
The Right to Freedom of Thought, Conscience and Religion

Everyone has the right to freedom of thought, conscience and religion, regardless of sexual orientation or gender identity. These rights may not be invoked by the State to justify laws, policies or practices which deny equal protection of the law, or discriminate, on the basis of sexual orientation or gender identity.
 
States shall:

a) Take all necessary legislative, administrative and other measures to ensure the right of persons, regardless of sexual orientation or gender identity, to hold and practise religious and non-religious beliefs, alone or in association with others, to be free from interference with their beliefs and to be free from coercion or the imposition of beliefs;

b) Ensure that the expression, practice and promotion of different opinions, convictions and beliefs with regard to issues of sexual orientation or gender identity is not undertaken in a manner incompatible with human rights.
