Ha ha, my alma mater! Back in the day, there was only one valedictorian and God was mentioned in commencement addresses all the time. Funny thing is this is a very conservative community (very close to Colorado Springs).
Did they refuse to release her final transcript to her future college or just refuse to issue the piece of paper? One denies you a future livelihood, the other a commemoration of past events.
In either case, here first amendment rights to free speech and freedom of religion were violated.
My alma mater as well (1991). LP has really gone downhill - full of political correctness now. I think it has to do with the influx of Californians that moved to the area and changed the Monument area from pretty conservative to very blue.
