Oh no no no, I'm an Atheist as well, I just have a whole different view on bad and good, like Kira from Death Note. I just know that bad people should die.
I see, I pretty much like the same except for Classic Hard Rock, I also don't like old metal like Iron Maiden, the only exception is Metallica, and even they aren't to good IMO. Bands I really like are Bullet For My Valentine, Five Finger Death Punch, Linkin Park, Three Days Grace, and System of a Down.
