Hinduism is a complex religion and a way of life, with a diversity of ideas on spirituality and traditions. It has no ecclesiastical order, no unquestionable religious authorities, no governing body, no prophet(s) nor any binding holy book; Hindus can choose to be polytheistic, pantheistic, monotheistic, monistic, agnostic, atheistic, or humanist.
So anyone who is trying to throw his own bigoted version of Hinduism on you needs to be ignored for the ignorant fool he is , and the essence of Hinduism is to be grasped.
