I agree with your synopsis - it points to issues with Dawkins' view
I've read two books by Dawkins but don't pretend to be an expert either in his views or in the religions that he effectively pulls apart. But here's the rub, IMHO of course:
Religion in some format has been a phenomenon pretty much since we've been in tribes.
To argue against it, to criticize religious beliefs 1) pretty much fundamentally opposes the right of someone to believe whatever they want; 2) requires a pseudo-religious fervour and zeal if you're going to do more than a cursory "personally I think you're loonies"; and 3) is destined to failure for any of 1,000s of reasons, complete lack of logical response not the least.
I think this is a much simpler argument. Cause and effect. There is a subset of people, seemingly more prevalent amongst the Muslim population but existing in many religions (and other areas political / nationalist / jingoist), that will react strongly, disproportionately and misguided for a number of reasons including passion, self interest, greed and a youth-ish need to smash things up, if someone else deigns insult facets of their religion / patriotism / football team.
Given the right environment, and the wrong comment in the wrong tone, I've seen similar (if not quite so international) reactions by Australian, British, American youths and one particular pub in the Greek isles a fairly emotional bunch of German kids.
To comment negatively to a religion, given for many people their individual belief is often a heartfelt thing rather than intellectual, is to insult personally. Right or wrong, that is going to happen. Pick on a buddhist and they'll hit you up with more love. Pick on a Muslim on the basis of his religion and he'll invite his cousins, mates and a bunch of folk he's never met before to smash you up.
Cause and effect. Given the repetitive and consistent nature of the Muslim-mob response over many years now, to think otherwise demonstrates willful ignorance. Personally, I'd say the people that made the video are revelling in the danger and hurt of others now facing the mob. But that's just me, of course.
