There isn't anything wrong with enjoying the culture of religion, or the history. Liking Flyleaf doesn't make me any less agnostic.. Being interested in how the Crusades were fought doesn't mean I'll start proselytizing.

Anywho, I can relate

The only good christian based films I've ever seen are Ben Hur (The original. Not that crappy remake from a couple years back) and The Ten Commandments.

I actually watched the first God's Not Dead film, but every single aspect of it was so poorly executed that I haven't even bothered with the other two.

You can love the Soviet Army Choir, and react emotionally to their music: That does do mean that you approve of communism! I too like negro spirituals music, but the words pass me by! (You can appreciate Wagner or Puccini without understanding German or Italian!)
On the other hand, to respect religion is to respect obscurantism, intolerance, idiotic do's and dont's without explanation, and the peddling of guilt complexes ruining the lives of hundreds of millions. It is respecting "the right" of jews and muslims to "save their souls" by hideously torturing to death their butchery animals and to cripple little boy's sexual organ without their permission. And it is to meekly agree to disagree with notions such as walking on water or flying around on winged horses! Tolerate all this? NO, NO, NO !!!

I don’t know of any of the mainstream Christian movies you speak of. If it wasn’t for Youtube channels like The Bible Reloaded, or CultOfDusty I wouldn’t even know they were coming out

Before being fully aware I'm agnostic, I sort of liked some of Christian music you mentioned, but I was uneasily aware that even singers I admired were proselytizing, which made the music seem fake.

Especially when popular Christian singers went secular, and I realized it was just a gateway to fame for them. Amy Grant comes to mind.
