Yuck hate that perspective.
That totally leaves out music at its best.
To me that's the purest form of religion,
which for me has more to do with appreciating what is beyond our understanding, than anything else.
Though in the real world I see religion first and foremost as a means to control and manage tribes and societies.
Well... I would add that "set of supernatural beliefs" has two sides. Those who believe, and those who make people believe. You can leave out the supernatural part of it, and you will end up with "politics" or "ideology". I often compare the three, because religious people tend to point out how are ideologies harmful, but "religions are good". Its same when christian say why his religion is true, while he certainly recognizes that islam is not.
