The 'clash of civilizations' is really a dialogue of the deaf. In Britain, the State has not taken religion seriously for maybe a century. And Muslims are not spiritual in a way that fits what sense of religiosity Britain has left.
The bureaucrats' operational theory is that just as Europe has 'secularised', so other 'faiths' that come to Britain will secularise too. This largely explains the decades-long complacency about clerics preaching hatred: it would pass just like Anglicanism is (said to be) passing.
