Rastafarianism is a fascinating religion. I don't think many Ethiopians immigrated to Jamaica, a few Rastas went there to help in a war with Italy, lived there for a while, then returned to Jamaica. It doesn't make sense that people would leave Ethiopia for Jamaica. Why not go to Western Europe or America?
Yes, as well as fascinating, it is also different and its ideology is very much respected.
Yes, not everyone has emigrated, but I say because wars, if they are actions that bring more pain, now emigrate to support a war that is not theirs.
In the end, these are things that only they will know.
Greetings.
