You seem to be ignorant of the fact that the Islamic world is incredibly diverse, with innumerable sects, traditions, and peoples. The Quebec law targets only the most extreme and retrograde sects of the religion, such as Wahhabism, where covering the face of women is still prescribed. 

This country needs a more nuanced debate on multiculturalism where we don't treat each large ethnic group, including a group as diverse as Muslim Canadians, as a single, monolithic entity. Things are much more complicated, but unfortunately journalists and activists are either too lazy or unscrupulous to be honest about the complexity of these issues. 

The picture painted by this article and many news commentators is that all Muslims, including let's say a North African moderate Muslim, condone and support all expressions of their religion, including the form of Islam propounded by the Taliban in Afghanistan. This is a ridiculous point of view.
