OK, I've sat on the sidelines long enough.
My grandmother used to say, "Every wash tub has to sit on its own bottom." None of us truly know who will make it in, and who won't. To be frank, we don't even know if WE will make it. Such is the nature of living a faith-based life: we beleive, and we act in a manner consistent with our beliefs.
When we see someone doing something wrong, and the action is directly against us, I think it is in order to address that wrong with the person.
When we see someone doing wrong, and the action is not directly against us, I think it is more appropriate to pray for that person while we are praying for our own salvation. "Judge not, lest ye also be judged."
As for food and drink (alcoholic and otherwise), the Bible and medical science both teach us that moderation is the key. Good health is a lifestyle choice consisting of diet and exercise.
When you begin to talk about people's occupations that is a slippery slope. I personally would not work for RJReynolds because I strongly oppose smoking, I probably wouldn't work for Anheiser Busch either even though I am not opposed to drinking beer (in moderation). At the same time, I don't have a very high opinion of pawn shops, check cashing places, and strip clubs either. But everybody who works in a strip club is not an exotic dancer so do you condemn the waitress, the security guard, or the cook in the kitchen? And the owners of such establishments are helping the community by employing people who might otherwise be doing other illegal or immoral things to earn a living.
As for the question that started it all, here is a repost of my answer: I am going to take the position that I am not a "Gospel Musician" but rather a musician who plays Gospel music. I also play Jazz, R & B, Pop, and Rock (although Gospel music is primarily what I play when I play "out"). If I had the opportunity to play in a jazz combo I would. If I had the chance to play in a R & B or Pop/Rock group I would probably do that as well. Heavy metal or country? Probably not.
That said, if there was a particular SONG that I personally objected to playing I would probably not play the song. "Adore" by Prince? Yes. "Erotic City" by Prince? Probably not.
