It takes a nation to protect the nation
Most kuffar do not realise that Islamic 'prayer' is not just a call to God, it is also a way of laying claim to a place. By repeatedly 'praying' in a space, the precedent is established that Muslims have a right to pray there. It then follows that if anyone is not totally respectful of Islam in that place, they have disrespected the religion and are deserving of censure or violence. This has been seen many times.
It is for this reason that Muslim armies often destroy the places of worship of their enemies, and build a mosque on top.
Anglican vicars fail to understand this principle, so are happy to let Muslims issue the call to 'prayer' inside their churches, thus staking that out, and claiming that space for Islam (don't forget also that every non-Muslim is a 'revert'). Catholic priests are a bit better I think - they recently denied a Muslim request to 'pray' inside Cordoba Cathedral.
