I agree with you.
I don't like the way Christians are singled out any more than anyone else, but they cannot form a prayer group in the hallway of a public school. They just can't do it. They were not asked to stop. They were asked to take it to a designated area and to clear the hallway.
The $64,000 question is not whether the prayerful students were told to move, but whether the administration has allowed other groups to assemble in the same area.
More like the back of the bus. How can 12 people block the flow of trafic in the Commons area, that is not a hallway?
