I would hate anyone, Christian or other, to push their beliefs on me at work, in hospital, street or anywhere.
So far we agree.
That is good right?
Your last post said, " It's about whether or not it is ethical for people in positions of authority to bring their religious beliefs to work."
You object. I don't. It is part of their personality.
I see the crucifix or the veil or the turban.
Fine.
They ask if I want a prayer and most religions I will decline.
If they persisted I would have a problem.
Otherwise not. It is called tolerance.

This nurse just asked once and immediately let if go.
The patient had no problem. I think most of us could cope with that.
