Muslim students have been holding prayer services in the basement of the chapel for the past two years.
If they've already been holding services for two years, they already know where to find them. And the traditional call to prayer is (a) disrupting to the 14,300 students who DON'T "self identify" as Muslim, and (b) an anachronism in a day and age when everyone carries a smart phone that can be set to sound an alarm at prayer time.
If the Muslims think they need a call to prayer, they should go somewhere that it's the custom. Do you think a university in Saudi Arabia would allow Christian services in the mosque, or allow a Christian hymn to be played or a psalm to be read over a loudspeaker every Sunday?
Every day I learn to despise liberals even more than I did the day before.
