Muslims in Europe are subject to systematic racism, i.e., institutional racism. Without tackling the European states' perspective towards Muslims which a good portion of the issue, they won't transform themselves. Europe's problem is not Muslims abiding Western norms, you just don't want them in Europe no matter what. Seek the part of the problem in yourself, not in Muslims. I am not saying Muslims are all good, sure some cultures are conservative.
And to be frank, you bunch complaining about Muslims isn't going to change anything. What is the solution in your mind? I have an idea, but hey... spill it out.

Mate, not so long ago (80s and 90s), you Germans were incinerating Turks' houses. It's hard to imagine for that generation and their children feeling at home. A good portion of the problem is
your culture which can converge to violent racism if not controlled. Next time when you think it's so good in Europe, and Europeans are so welcoming, think about it
