Hindu is one who is following a long (from thousands of years, more than five thousand years)traditions of this land and adapting to the new demands as per the need of the time. Not just one who goes to temple. Hinduism it self has manifold religions which are beliefs of the people of the land or races which have joined this ocean.
And there are many hindus who dont go temple also. They are born as hindus, even though they dont accept god at all they respect the traditions.
