Yeah I am being raised in a Christian house hold. My advice to people also being raised in a house hold, and about heavey metal, is to just hide the albums, and never talk to your parents about music, or at least heavey metal. My parents are very crazy about stupid stuff like that.
My parents made me through away my Amorphis cd, which wasn't a big loss, but it made me realize, I need to find better places for my "devil music" like Cradle of Filth, Dimmu Borgir, and Emperor. I listen to eviler things than those bands, it's just I have to sneak everything in, hide it, and then listen to it on headphones or with the door locked to my room.
The funny thing is, this music hasn't ever altered my view of religion. I believe there is a god, but that's about as far as it goes. I mean I'm forced to attend church, but I have serious doubts about all the things they say.... so metal has never altered my view on religion. It might if you want it to, but who cares what one believes in?
