The London Police were giving grief because of flyers that had a puppy on them (a Police mascot) because the muslim community was all upset at the 'filthy' animals image being around.
If you want is the Western way go there...but stop trying to change the West into your kingdom.
IIRC the fuss with the puppy was raised by one or two obnoxious loudmouths and then carried on by PC non-Muslims. Most Muslims quite sensibly didn't care.
As for the second point. The problem is that Christianity and Islam are both expansionist religions. Part of what this means is that they only thrive when believers have a feeling that their number is growing. The collapse of Christianity in much of Western Europe pretty closely coincides with the idea of not trying to convert the world. Believing Muslims don't want the same thing to happen to their religion.
Interestingly the number of believers doesn't actually have to expand as long as current believers feel like the number is expanding (in other words perceptions are more important than reality). US Christianity (much more robust than European versions) maintains an illusion of continual expansion by (basically) converting and reconverting the same people over and over again and this is not unheard of in some Muslim circles too (as is making it difficult or dangerous for Muslims to convert to other religions). Another tactic when Muslims are in the minority (practised in a lot of western Europe) is to self-segregate as much as possible and whenever possible get the majority to grant them concessions.
