And who defines this obscure "true understanding" of Islam? Is there something called "true understanding" of hinduism or christianity that the world abides by that you can neatly package up and stamp a lable on a group of people? Of course, it is very convenient for you to say that this true understanding of Islam is attained by these spineless cowards because that supports your thesis. Simply put, majority of religious muslims around the world will tell you differently. In fact, they will flat out disagree with you that no I am a muslim and I don't think its necessary to be "duty bound" by any "killing of the kafirs" Says who? You throw obscure Quranic passages and hadiths and they will tell you no it doesn't mean that at all. Look the fact is these terrorists don't have mononpoly on what Islam means and what you ought to be duty bounded by. There are a billion muslims world wide and by far majority of them are not blood thirsty vampires. I don't deny that these terrorists are muslims and they are using religion as there argument to recruit and kill but if your thesis had any waters; not thousands but millions of muslims would be out blowing themselves up. That's just not true.
