For the jihadists, Muslim women who embrace Western mores, and wear tight jeans or mini skirts, are hated symbols of corruption that need to be eradicated. For the ideological mentors of Breivik, a similar disturbance comes from the burqa, which is banned in France and Belgium, partly thanks to their efforts.
In the 19th century, when Muslims were looking at Europe as an example, they were independent; they were more self-confident. In the early 20th century, with the fall of the Ottoman Empire, the whole Middle East was colonized. And when you have colonization, what do you have? You have anti-colonization.
While no Muslim worthy of his name would lose his respect for God, the Prophet Muhammad, and other symbols of Islam, he might well refrain from using legal prosecution or violent reaction to those who do not show the same respect. My basis for this claim is nothing other than the holiest source of Islam, the Quran.
