I have not heard church bells for Sunday services in years.
The noise from the bells offended the Saturday nite drunks.
You only need one person to be offended by the noise of the call to prayers. Hopefully it will be take to the supreme court to protect that one person from being forced to listen to it.
I cannot imagine having to listen to something in Islamic being broadcast across the city several times a day. I should think that would be right up there with water torture!
