The increasing Islamisation of Pakistan and antagonism against a majority Hindu India has forced many Hindus to leave Hinduism and convert to other faiths such as Buddhism, Christianity, and Islam. Such Islamisation include the blasphemy laws, which make it dangerous for religious minorities to express themselves freely and engage freely in religious and cultural activities. The promulgation of Sharia, Koranic law has also increased the marginalization of Hindus and other minorities.
