Do you realize this issue is about Muslim kids wanting to have their weekly mass on a day which is normally a weekday & regular school day? 

Jewish and Christian kids do not have this challenge, because Saturdays and Sundays are weekends and whoever wants to go to the synagogue or church can do so without interrupting their own work or school routines. 

The reasonable accommodation here for Muslim students AS PER THE LAW is to allow them 20-30 minutes of their own time during school hours to hold their weekly mass in a secluded room, in a manner which is not burdensome in any way to others. 

No one is demanding we turn schools into mosques. These prayers have been going on for 20 years with no objections from anyone. The only reason why its in the national conversation right now is because a small group of intolerant bigots are on a crusade to disallow Muslim kids from exercising their legal rights.
