The problem is, that when your religion is based upon a selective naive literal interpretation of an ancient holy book, your religion can literally be anything that you want it to be.
Religion ... pure and faultless is this: to help widows and orphans in need and avoiding worldly corruption. James 1:27
How is that a "selective naive literal interpretation " and why would you use the word "religion" for anything else other than meaning to help widows and orphans, etc. or as you say, "be anything that you want it to be."
