I can understand where U R coming from. Personally, I love the music cos of the sound. Some stuff I have had to throw out cos it obviously speaks against my best friend (J) and I wouldnt headbang along to that.
I have, however, helped a full on black metalhead, who also considered himself to be a satanist, find God through just hangin with him and chatting about music. We had common ground, and thru that we formed a friendship, and one night, God gave me a vision for him that really changed his situation. He was ready to commit suicide before that. Now he doesnt deny God and hopefully one day that may lead to a deeper relationship with Him. But I can tell U this much, he HATED Christians and wouldnt have given me the time of day if I didnt know the words to Angel of Death, or The Trooper. So for that guy's sake, I'm glad that I could relate to him and him to me. Know what I mean? Just a thought.
