When I was in High School there was a Christian Club....called the Navigators who were given use of a classroom at noon hours to meet and pray. I think you would term them, and they would be glad to be considered "devout Christians".
  These "devout Muslims" are not asking for a special room to be adorned and used exclusively as their prayer room, as some reactionary obviously anti Muslim posters have falsely claimed.

Take his test to see if you are biased or truly against anyone regardless of their religion  being allowed a quiet space in our schools to pray.

Ask yourself this;  if there is a Christian or Jewish group in this school that has , for years, been granted a vacant classroom to meet should they be now told that they are not to be allowed a vacant classroom to meet in ?
