First of all, you should really take Old Thunder's advice and use paragraphs; I literally didn't read half your post because of this, which is a shame, because I imagine it was thought-provoking. I can relate to your dad; there are times when I am super-religious, there are times I step away from it: I always think "What are Christians allowed to do for fun?" Old Thunder explained to me Highway to **** isn't literally a song about celebrating going to ****, but my concerns over that were similar to what you're saying; what if I like a song that's blasphemous? This is one of my favorite songs, where the singer is essentially saying "You can't prove God exists; you're not praying to God, you're praying to yourself"... how can I justify loving this song and being Catholic, doubting the Lord? Life is too open to be pigeon-held by religion; that's where I'm at right now. No one is wrong for what they believe.
