That's a might big chip you have on your shoulder. You claim to know about Christianity, but you know what, you don't know jack. Perhaps you should open your ears and mind and close your mouth.
And FTR: I am a pagan. A Goddess worshipping, tarot reading, spell casting, Pagan. And I have been on the receiving end of crappy Christians telling me I am hell bound, threatening my life and offering (most magnanimously) to pray for my soul. And not a one has been a nurse.
I've been critically ill, and not a single nurse talked to me about God or Christ. Not a single nurse prayed over me. If they prayed for me, it did me know harm. I got excellent care, even though they knew I am a Pagan. They provided me me with excellent care because they were good nurses. Not a single one told me how awesome Jesus is. And I live in the bible belt.
You are just as judgmental as you are claiming they are. You need to take off YOUR blinders. The attitude of yours is only going to hurt you in the long run.
