Not only in Hinduism, there are such things in every religion and every corner of world. It is you who determine which way you want to go. Let them do what they do.
And Hinduism one of the religion which faced repeat distraction from the external forces. from the magnolias, some mulim worriers, mugals, Portuguese. Dutch. British and still it is under attack from external and internal impact. But still it is there and we can feel that.
Proud to be a Hindu.
