If people are converting due to poverty the government should take steps to check it. If conversion is taking place due to caste factor then steps should be taken to annihilate caste as an institution and if somebody is being converted with physical force then law of land should be brought and a case of fraud under Section 420 should be registered, said Dr. John Dayal, eminent human rights activist and Christian leader.
“But if they are converting out of free will from any religion then they must be allowed to do so. Conversion is a constitutional right. I support conversion. Religion and nationality are the only two things that a person can change. Many NRIs (Indians) have thrown Indian passports and embraced foreign nationalities. Even Indian gurus are travelling all over the world, spreading message of their spiritualism and Hare Rama and Krishna sect has been converting tens and thousands of western people into Hinduism,” Dr Dayal said.
What he said was forceful conversion is unconstitutional.. I just copied what he said..read it and tell me if u find anything wrong..
