"Disturbed" because someone shares a thought with someone else.
Yeah, that's why I'm disturbed.
There's a reason that if you look at the list of majority Muslim countries, few are places you'd feel comfortable in for even a short amount of time as a tourist, and even less if your wife were visiting with you (and that's after excluding Iraq, Libya, etc). Muslims in several majority Muslim countries are butchering Christians (and sexual minorities if we want tottalk about western tolerance) at the level of tens of thousands per year. Conversely, millions of Muslims living in countries where they are minorities do not experience the same level of danger. In fact, they are an outsized danger to their host countries and cause significant security expenses.
You assume that Muslim countries reflect "true Islam" (or truer Islam, at the very least), while Muslim immigrants reflect some kind of watered-down or Westernized version--i.e. not truly "devout" Islam. First, there's no way you can make that claim analytically without collapsing into fallacy. There's no pure Islam, there are only variations of it. It doesn't become less devout simply because it's not being practiced in a nation that follows Islamic Law.
Second, you deny history and context in favor of the present. Historically speaking, Islam has been more tolerant of other religions than Christianity has. It's only over the past century or so that Islamic countries have become the scapegoats of religious intolerance that we know today. For example, Muslims ruled India for a long time before WWI, and yet many Indians weren't practicing Muslims and weren't persecuted for it. The state of many Muslim countries today has to do with politically violent reactions to (yes, I'm going to say it) Western occupation and exploitation. The establishment of radical governments has less to do with the radicality of religion and more to do with political power and unrest.
Third, your comment implies that Western stability and tolerance is due (at least in part) to Christianity being a more tolerant religion than Islam. This is beyond true or untrue--it returns us to the quandary of my first point. Medieval Christianity wasn't more tolerant, but modern Christianity certainly appears to be. Which version is more devout? Most practicing Christians have been able to leave behind the demands of Leviticus; in this respect, it might appear more tolerant. But if we're speaking of devout religion, then we'd also have to say that Christianity is incompatible with Western modernity. All that is compatible is adapted, or adulterated, forms of religion; and as is clear from observing Islamic communities in the U.S. and elsewhere, adulterated Islam is easily compatible with Western modernity.
The tolerance of the West has nothing to do with Christianity being more tolerant than Islam, and the intolerance of Muslim countries has less to do with the details of radical scripture and more to do with the history of Western meddling and the hunger for political domination among local governments.
