[Starry Night]

Even though she most likely means well, the way she went about it is definitely controlling and not right. I would tell her that I am an strong, grown individual that makes my own choices including religious ones. It also means mutual respect. Assuming your mother is like mine, she would probably be extremely dismayed, but with these kinds of things...you just have to put your foot down, honestly.

One of my philosophies in keeping quiet is "If I go ahead and get riled up, I'm just making myself more angry." If she says anything about it, walk away. You do not need this kind of stress.

Good luck with this situation.
