Hinduism is the name given by britisher to those people who follow vedas and agamas and accept baghavdgita and Ramayana as Sacred text, There is nothing called Hinduism as such,
As you can see how many people follow this religion is very very few. How many people know sanskrit or studied vedas and followed all the religious duties.
Now a days Hinduism exist only in theory and not in practice.
Those who call themselves as hindus and form a group speak about thier rights, basically are groupism
