Crosses

Crosses in every room at Washingon D.C.’s Catholic University of America are a human rights violation that prevent Muslim students from praying.
That’s the complaint to the Washington, D.C. Office of Human Rights filed by a professor from rival George Washington University across town.
GWU Law School Professor John Banzhaf takes the Catholic institution to task for acting “probably with malice” against Muslim students in a 60-page complaint that cites ”offensive” Catholic imagery all over the Catholic school, which he says hinder Muslims from praying.
Baffled Catholic University officials say they have never received a complaint from any of the schools Muslim students.

Also:
The complaint further objects that Muslims must pray at the school’s chapels “and at the cathedral that looms over the entire campus – the Basilica of the National Shrine of the Immaculate Conception.”
You can read all about it here but basically Muslim students have enrolled at a private Catholic University. After requests by the students, the University gave them use of a room in which to offer their prayers. The complaint is that the room contains a cross (as does EVERY room in the university).

What am I missing here? They've been given a room...it's a private CATHOLIC University...and they're complaining about the crosses?
