God bless those rastas. Arrested Development put out a song a while back based on Revelation 18, the part where Jesus calls his children to get out of Babylon. And they state plainly the need for that kind of departure from the dictates of a contrary society. The song is called Hit the Road, Jack, and I don't know what CD it is on, because I couldn't find it anywhere.

No one, nowhere will escape the day of judgement
Ok, I dare you to do right instead of wrong
Babylon will fall and when them do
There will be peace for us all
But until that day, I stress that you stress that we go away

Hit the road, Jack, and don't you come back no more....

...you think you standin hard as a rock but you ain't intimidatin as a pebble
You look tough but when you speak your voice falsetto like Aaron Neville
And you ain't livin for God then who you livin for, you a joke slowpoke
Afraid to see sin within that makes you yoked...
