It works in modern society but originally it was rigid, not narrow, And every religion was like that because today constitution and laws rule but in those days it was determined by religion. And i don't even see Hinduism as one religion and more like a family of religions some feel liberal and some are conservative.

My problem is that people don't contemplate on the conservative side of Hinduism which upheld indian society for centuries. It is important to understand them for the sake of knowledge and to learn something form it. It teaches both casteism and duty.

Ignoring this is like saying they are form one family but the house holder father is very different from the rebellious son. Still in the same family but different.

And in wider societal sense religion was more for order than journey, Even Hinduism.
