Since its not the ENTIRE group wanting to ban it:

The move was led by three recently elected student trustees, who ran for office wearing revolutionary-style berets and said they do not believe in publicly swearing an oath to the American flag and government at their school. One student trustee voted against the measure, which does not apply to other student groups or campus meetings.
I think they SHOULD have the POA said. If it was unanimous to have the pledge banned, then I'd say ban it. But it obviously is not unanimous.

IF you don't want to say the pledge, then don't say it.

IF you are offended by parts of it (under god or other parts), then don't say it.
