BF if I were in labor and there was any kind of religious symbol...I don't care what kind...they better get that crap out of the room cuz the hospital ain't a church, temple, mosque, synagogue or other place of worship so I would not want to see it then...and you can bet I wouldn't go to a religiously affiliated hospital if I could help it.
I think when you're in labor, you have much more important things to worry about then whats on teh wall. She was absolutely stupid to complain about something so ridiculously trivial. It's not like her baby would have even comprehended the cross, were it somehow born with it's sight working perfectly, which never happens. It would have just seen a shape and probably would have tried to eat it or something.
Religious fanatics need to give it a rest, if she didn't like it, she coulda just ignored it.
