To what extent are Hindus sectarian? For example, do most Hindus belong to a sect, e.g. Shaivism or Vaishnavism? Do they only go to temples within their sect? Does the entire family belong to the same sect? Are marriages arranged only within that sect? Are there many families that have been part of that sect for many centuries? Are children's names picked according to the sect?
I had thought that most Hindus were not sectarian, but then I saw a post or two that led me to think otherwise.
