Well with heavy metal there is the King Diamond problem, and the Glen Danzig problem. So there are actual satanist performers in heavy metal, of course they’ve never been big acts either, they don’t make Ozzy or AC/DC money. And with good reason, they kind of suck. But in the main section of heavy metal I think the satanist crowd is in line with the norm.
Some of that running to the things people warn them against is just rebellion. We all do some of it. To this day, even with my teenage years nearly 2 decades behind me, I don’t like cheeseburgers, and I know that the reason I don’t like cheeseburgers is my mom loved them and one of my first bits of rebellion was cheeseless burgers. Now I know cheeseburgers and your immortal soul are kind of a weak comparison but there are parts of that which hold true, part of setting up your own identity is picking things to rebel against, and sometimes it’s going to be matters of taste, sometimes it’s going to be rules, and sometimes it’s going to be warnings against legitimate danger.
That’s where it becomes important to teach your kid to think, the question for teenagers isn’t “are they going to do something stupid” it’s “were they given the tools necessary to survive”. And that’s one of the things I think the condemners miss, somewhere along the lines they started treating their faith like it’s fine china that needs to be protected, they forgot that faith is supposed to be a shield that protects you. by being constantly afraid of things that might maybe wound their kids’ faith they’re taking away their kids opportunity to use their faith. They should be instilled with enough faith to be able to listen to a Danzig album and say “that sucked”.
