If she is that naive then you are better off. There is no reasoning with crack pot religious thinkers. They see only one road of thought. Condemn everything they don't agree with and blame others for their own fears. Just accept it as so and move on. Do what you want to do and don't let her twisted ideas infect you. The concept of God is about love, empathy, kindness, understanding , patience etc. your TV viewing will hardly come up on Gods radar. I am quite sure God is having a giggle watching Supernatural cause the angelic realm is benevolent not malevolent and those story lines fell of the wagon the moment they detoured from the cool creepy scary story lines to the angelic fight club between Cas and the other angels and every demon ever known to man. That's just my opinion of course. Anyway. Chin up. I am sure in your life time you will come across more religious crazies. They are everywhere

I onced worked on supernatural, I guess I will have a swell time burning in hell.

Oh, dear Granny, that show is literally swarming with angels of the Lord!!! How can you not love it?? ;)

I'm a Christian and I watch Supernatural. I just don't let my core self/values be swayed by it, or any other show.

YDI. Supernatural sucks.

That is the reason i dont tell her about the show and how i actually have the anti possession and the angel warding sign tattooed on me

That's completely messed up. Sure, the show is freaking awesome, but as long as you can distinguish fiction from real life, nobody should disown you over your entertainment preferences.

Keep watching Supernatural, you don't need that kind of negativity in your life.

Call Cas. He'll change her mind.

I would disown you for watching Supernatural too, though not for religious reasons.
