Probably because Muslims in Iran killed thousands of innocent bahais in the 70's and 80's. The same can be said of Christian's, Jews, Catholics ect. No one on earth can explain god or what he or she wants. Only real rule to adhear to is if you decide to wrong someone or kill them how would you feel if it was done to you. Hold your child and think of how horrible it would feel to have someone kill them and realize that when you contemplate to commit murder over a text that was written 1000 years ago. When you lose your ability to feel guilt and remorse you cannot be called a human being.
