See the problem is that you cannot follow the whole book unless you are a priest or a Sadhu(indian).these religious books teach us a lot of things but we cannot follow them all in our daily lives but yes you can follow some teachings.Being in this busy world almost doesn't allow us the time to follow the books properly.
It is usually the ones who follow the bible to teh word that really get mixed up and become so strict taht they forget the heart and they have then lost the most important meaning of the book. I remember catholic school where the nuns were built like nfl linebackers lol and it felt worse then as if I were going to military school. As far as fights, thats the hardest thing to do to walk away from for most people, but it has always been the easiest for me since i have always leaned towards being a pacifist. My weaknesses are my extreme sloppiness and my individualistic nature.
Thats what makes us all so unique. We each have our strengths and weaknesses
I will say that that's generally what turned me away from organized religion the most (if I had to name one factor). I couldn't stand all the Christians who were just in it because of Pascal's wager, especially since they are often the same ones who take on a "holier than thou" attitude.
A true follower would just try their best to help their fellow man. It wouldn't be a contest for heaven points.
I highly doubt most people follow their books all the way. If they did, we would be living in a primitive world with a lot more fighting.
