We're talking morals here. Good financially isn't really what we're discussing. Especially relating to OP. IOf you think bad things don't exist in heavily religious areas you are incorrect. There's lots of good and you'll find like minded people but you know that's not all that's there.

Demand is what rewards money. I don't want my kids thinking some stupid rapper is cool.

We would also have a lot of what the bible says is wrong (but also right but we ignore that bit). Slavery is in the bible, that's fun. Killing our enemies is in there too (Book of Luke). A lot of very old fashioned ideas on woman. Homosexuality etc. A lot of people have been hurt for Christian values. The good ones are often reserved for certain people but I think they should be for everyone.

As far as I'm aware, religious christians today do not practice slavery. So your argument is false.

Even before Atheism and mixed cultures did these things exist. Prostitution isn't called the oldest profession in the world for nothing.

At least it wasn't legal. Today they call it porn to avoid calling it prostitution.

No you're not. Some rappers are still Christian and believe in god. Kanye is Christian btw. Bad things have existed in our time since before Christianity was a thing and Christianity didn't stop it. Look at what they did during the Cruscades. That was terrible.

The crusades isn't going to affect you today. Allowing stupid rappers to succeed and make society dumb, and allowing celebrity culture to dumb down your kids will. And allowing these things to exist and being accepting of them just because you feel like the alternative is to commit the crusades is retarded.
