Earlier quoted context omitted.
It seems they are missing an important factor, namely 4) the personal, cultural and economical impairment due to the religion of Islam. Nobody has time to thrive when they have to pray five times a day, when almost every thought and action is dictated by an old book and when half of their human potential is hidden in cloth bags.
You could not be more wrong. I am a software engineer, and I pray five times a day. My wife is a physician, prays five times a day, and wears the headscarf. If our household income is any indication, we are thriving just fine.
It is obviously inaccurate to write "nobody" and I am sorry if I have hurt your feelings by this rhetorical device. I've merely pointed out a general tendency that Islam numbs social, economic and scientific progress, i.e. that the influence on the conflicts in the Arab World with regards to religion is not just a matter of differences in beliefs, but rather an underlying condition of a kind of belief which prevents progress. The niqab and burqa, the excessive structuring of day-to-day life, Islamic extremism, as well as oppression of women, gays and atheists are simply symptomatic examples for an overly binding religion. I've also only pointed out that it plays a significant role in the grievances in the Arab World, not that is the only cause.
