Yup you got the point.
You know what, i will go on and say thing one thing risking absolutely destroying this thread as it may invite all sorts of flaming and religion troll posts. Still, i guess you may be able to understand this.
Thing is, you go to a doctor to discuss your medical issues right? and a car mechanic for you car troubles? what will happen if you ask a car mechanic about your blood pressure issues? Unfortunately we people do this for all forms of science and other question except religion. Just like any other source of information and knowledge where you just consult the experts, it is unfair to judge religion based on debates and discussion with people who are not the experts but merely the followers. All these questions pointed out here must have answers to them but just as i cannot tell you what to do if you car suddenly breaks down i am not able to answer in detail these questions either. Now it depends on oneself that if he actually is interested in acquiring the information he can put in that extra effort and get it from an authentic source.
