Personally I've never understood the taboo of listening/watching "secular" things.
We need a challenge, art should ideally make you think or question things. Right? So why cut yourself off to a potential growth experience like that? Art shouldn't just conform to your worldview, it needs to broaden it.
Also I think some basic analysis techniques are warranted when deciding where one's threshold is. All too often I have seen religious people deem a song or book or whatever "bad" or "promoting sin" because they took something either out of context or interpreted something very literally.
I mean people can interpret things as they wish. But it does impact on what message they can get from said source.
For example, we had to dissect this song for class once. I'm not Jesus by Apocalyptica ft Corey Taylor. (My teacher happened to be a fan, don't ask.)
Now the only time I had heard of it before class was when my Christian friend wasn't sure if she should listen to it. Apparently her religious leader claimed that it was promoting atheism and mocking Jesus. Supposedly because of the lyrics "I'm not Jesus, Jesus wasn't there." But if you actually look at the song as a whole, it's actually about child abuse! And based on the lyrics, one can gather that said abuser was a member of the cloth and using religion as a shield. It's not so much about "mocking god" as it is an angry kid trying to come to terms with the abuse, confronting the abuser (either literally or metaphorically) calling them out for their hypocrisy among other "flaws", refusing to forgive them and expressing a mixture of confusion and resentment at the religious promises made to him/her as a child. The lyrics "I'm not Jesus" is a reference to the fact that they will not or cannot ever forgive said abuser. Which is hardly "anti Jesus/god" imo.
Take another song. Gangster's Paradise. (My god that was EVERYWHERE when I was in primary school.)
Now more often than not, I have seen it being accused of promoting the ghetto lifestyle to the youth. Which always baffled me because pretty much the entirety of the lyrics do anything but glorify "street gang culture." In fact, it's more a lamentation of the seemingly never ending cycle of the youth being sucked into such a life, without getting real help and trying to promote a sort of wake up call to try to stop it happening in the future.
Then of course you have all the religious (mostly very strict Christians) backlash against Harry Potter, which ironically enough, promotes all the exact same teachings of Christianity. Harry is even a Jesus within his own story. D&D, 80s children's TV (no seriously.) Even freaking Pokemon was being denounced in some Churches!
My point is, people can interpret almost anything as "evil" or "unsafe for religious people."
But one should make up one's own mind at the end of the day. A lot of that may well come down to how one interprets art, whether that be music, literature, paintings or even television.
