Oh, this sounds all too familiar. When I was about 16 and still lived at home, my parents did the same thing. It was mostly my mom who is uber-religious, but she got my dad to help her in attacking my cd collection. They got ahold of my cd case when i was gone and took about 15 cds from me. When i got home, they tried to tell me it was evil and was going to corrupt me or some stupid shit like that...they went through the lyrics with me to tell me what was wrong with them. They took some of my favourite cd's I was so pissed off, but they wouldn't tell me where the cd's were or what they were going to do with them. Luckily, Blackwater Park (which was the only cd i owned by opeth at that time) was in my other cd case. I had never been so pissed off at my parents. At least they offered to pay me $10 per cd...they said i could only use it to buy "Christian" music. So I went online and bought some mediocre "christian black metal" like Slechtvalk, Horde, Kekal, etc. none of which are all that great (but not terribly bad music)... It sounded like "evil black metal" music so I played it all the time really loud when they were at home. hahaha, they thought it was satanic until they read the lyrics. that shut them up, hahaha. Stupid parents, so delusional. I only bought a few of these "christian cd's" before I just rebelled and re-purchased some of the cd's they had stolen from me. Then a few years later i moved out and now I am happy to be able to make my own fucking decisions and me and my parents get along fine.
