So you're suggesting the immediate withdrawal of property rights for all Muslims?
Also, are you sure that there are no Churches in Islamic countries? You might want to check your facts.
Oh and finally, yes there is a problem with Islam in our society, but do you think that the best way to tackle intolerance is to become intolerant ourselves? Personally, I am a proponant of attacking extreme forms of Islam but allowing those Muslims who don't care for such things to live in this country and worship here.
The problem with all-out attacks on Muslims (which is what a refusal to allow the construction of Mosques would be) from Britain's point of view is that:
a. It creates widespread resentment which causes more people to sign up for the extremists' version of Islam.
b. In a similar vein, it would prevent the Muslim community from taking an active role in solving the problem from within - something which I believe needs to start happening PDQ.
So, whilst I can understand your frustrations, I don't think you've thought this through.
