Gharib, the prevalent attitude in the west is a gross ignorance of Islam and what it does and does not teach, without even getting to the the myriad of nuances found in the opinions of your so-called "scholars". The vast majority have never even seen a Qur'an, let alone read one from cover to cover, in any language, let alone studied it for years on end. The point is that the overwhelming majority of Muslims believe the Qur'an is the literal word of god. Christians can easily dismiss what is in their Bible as being the fables of a bygone era, mythological tales created to explain complex aspects of human nature and the human condition. Due to the nature of Islamic scholarship and how opinions are given credence, Muslims are not quite so unlimited in their ability to be critical of their single source text, though the hadiths are a different animal altogether.
In regards to seeing Muslims as being terrorists, it is extremely unfortunate that so many have had the religion they love hijacked by a lunatic fringe that has a penchant for behaving badly. If only there were not so many groups to cite and so many terrible incidents - in recent memory - for people to draw on. For example, as soon as I heard of the shootings in San Bernadino, I immediately assumed that the shooters were Muslims. My reasoning was simple. There is virtually no other group of people that is giving rise to this type of virulent strain of killers. Though it is important to remember that all Muslims are not fanatical terrorists, it is also fairly accurate to say that a good number of terrorists these days, sadly, consider themselves to be devout Muslims - regardless of what others think or say about them. In no way should people hold average Muslims responsible for these acts and violence or acts of retribution against average Muslims should be dealt with severely.
Personally, I don't know what the answer is, Gharib. I respect you and I wonder if you have any ideas?
