It's not that there are too many Muslim terrorists. Most Muslims, and even most Christians, are not violent people, nor are they foaming-at-the-mouth Fundamentalists, and certainly today Christian terrorism is a thing, albeit absolutely nothing like it was centuries ago. Rather, the issue isn't of varying interpretations or the behaviors of Muslims, or even an issue solely with Islam, but that you can take examine the two books of the two most wide-spread and dominate religions around the world, with one of those religions using both books, and find that while some will focus on the love, peace, and tolerance to be found, the real issue is that many turn to those books to find justification for their wickedness, and there is no short-supply of passages, in either book, for them to declare their own ways of evil the will of God himself.
It's also an issue of how we don't like to question faith, and even view it as a virtue. Living in rural-Conservative America, this means my rights hang by a thread and are in peril with Mike Pence having the power he is set to wield (he was bad enough as governor). But if you don't have faith in this god, even if you don't have a problem with homosexuals and transgenders, just as long as you have faith you're aren't faulted; to not have faith is, very literally in the eyes of many, to be viewed as an immoral person who is fundamentally incapable of doing good. And, of course, anytime you try to upset the norms of the status quo, in a way that is truly meaningful and can advances causes and struggles, regardless of what is going on, most people will tell you not to and that it's just the way things are. But, when we do question faith, so very often and typically people are very eager to eviscerate Islam, but they somehow give Christianity a free pass, even though Muslims are instructed to read the Bible, and the Bible is as bloody tyrannical as the Quran. We so desperately want to blame it all on Islam that we are even reluctant to acknowledge there is a fundamental difference between Muslims who were born/raised and culturally Western compared to those who were born/raised and culturally Middle Eastern and rather just pretend anyone who reads the Quran and becomes Muslim is going to go blow up a public building, much like we were to believe listening to heavy metal would cause you to go crazy and commit suicide.
There is no reason to be afraid of Islam or Muslims. Rather, instead, we must be fearless in applying the lens of critical thought to all religions.
