Being a Hindu, I must keep my identity by worshipping Hindu Gods and Goddesses. But, if you ask what should the role of a Hindu in a multi-religious society, I prefer to behave as a decent and law abiding citizen of the country. If you ask whether I love mankind more over castism, then my answer is yes.
If you say "Does hypocrisy have any role to play to appease other communities?" My answer is NO.
Still I should say, there is one and only one eternal force. But, religious belief never finds any reasoning.
