In Jamaica, it is a religion about tolerance and loving everyone. In America though, it is celebrated by college pot smoking middle to upper-class white people. They are just finding more excuses to get high. They could care less what the actual belief is, in fact ask any of these "Rastafarian" college students about their faith. They either don't know anything about it, or are too up on drugs (not just pot) to make out an intelligable sentence.
"rastafarian" college student: "DUDE, I just got back from like... spring break, and I learned about this religion and stuff.. anyway.. there is pot in it. I converted that night"
regular college student: "you're an idiot"
