If one has criminal instincts, he will not bring religion in picture, like many criminals who are in every religion.
Who will show Islam as reason to fight against non-muslims? Those who are influenced, brainwashed by Islamic Mullas. These brainwashed or braindead peoples logic comes from the book not from their brain.
If there are good muslims , it doesnt mean Islam is good. They are not influenced by Islam or they compare themselves with well educated, cultured hindus, atheists and the influence of Islam is subtle on them.
At the end of the day it is not good muslims that we should consider for deciding nature of Islam. It is the Islam or the potential of Islam to create criminals and murderers that we need to consider. It is the statistics of incidents in the world that we should consider. It is the experiences of millions of people that were effected by Islam that we should consider and certainsly not your good muslim friend that we should consider while deciding the nature of Islam.
