We can only go by the explanation provided by the Indian representative to the UNHRC - that is that India's Constitution recognises the freedom of religion and that the country wants the international community to work together to eliminate intolerance, prejudice, and violence against religious followers.
His full remarks are below, and a digital recording of the proceedings may be found here.
India rejects firmly and unequivocally all forms of religious
intolerance and all acts of religious hatred, discrimination and
violence. India is a multi-lingual, multi-religion and multi-cultural
nation. Unity in diversity has been our civilizational motto. We in
India celebrate our diversity, as reflected in our abiding respect for
all religions and cultures. The Constitution of India guarantees to
all citizens as a fundamental right, the freedom of conscience and the
freedom to profess, practice and promulgate religion. It guarantees
equal respect for all religions and peaceful coexistence of all
religions. It has been on of the foundational tenets of India's
secular polity and society. Inspired by the philosophy of the religion
of humanity, India has always been committed to human rights.
It is regrettable that there has been an increase in the prevalence of
phobias against followers of various religions. In various regions of
the world, we have witnessed defacement and destruction of temples and
idols, glorification of desecration of idols, violation of Gurdwara
premises, the massacre of sick pilgrims and numerous other acts of
religious intolerance. There is a need for the international community
to recognize the instances of intolerance, prejudice, phobia, and
violence against followers of all religions and work together to
eliminate them.
Mr. President, the world is one family. It provides the basis for
elimination of all kinds of religious hatred, discrimination and
intolerance directed against followers of all religions. It is high
time that Member States join hands to build a culture of equal respect
for all religions and their peaceful coexistence.
