Haille Sellassie as god?

I had a conversation the other day with some of the kids from the academy about reggae and religion. Most of the boys seem to be taken by Rastafarianism. They tried to point out that the Rastas are the only people in the community not stealing and killing. They live fairly peacefully and other than smoking dagga (weed) they don't do anything bad. After our conversation I figured out that the Rastas use weed as their sacrament and their god (Jah) is actually a man they believe to be the incarnation of the last four manifestations of God. I further found out that the Babylon they preach against is basically western culture. I said that even though they may not steal or kill they don't believe in the same God and it is only through a belief in God that true transformation and forgiveness can take place. I tried to explain that the Rastas are not trying to make their communities better but are actually making them worse through the use and selling of their dagga (weed).

One of the boys then brought up the fact that under the guise of "Christianity" Africans were taken from their homes and brought to America or other Western Nations as slaves. This was a major point for him and rightly so. I apologized for that dark time in our history and agreed that this period was evil and wrong. I tried to explain that through the Bible and the message of Christ's forgiveness we can see that this "Christianity" was not a true belief and following of God's law. The boy then said that I proved his point of Christianity having evil views by acknowledging this past and he was through with the conversation.
I took a look back into African history and it is "white Christianity" that brought the slave trade and Apartheid. Apartheid was created in the theological department of the white university in Stellenbosch, South Africa. It made me realize that to many non-whites Christianity is a white, oppressive religion.
Our conversation ended there for the time being and has made me wonder and struggle with the idea of being a white Christian here in this country. How can I be effective in bringing development, community empowerment, Christ, and education to this community if I'm a white Christian? There is little differentiation between people that call themselves Christians and those that actually live a life dedicated to Christ's teachings (much like Christianity in American politics). In this same way there is little differentiation between Reggae and Rastafarianism for the boys here and I wonder how to bring the true Gospel to these kids given our pasts? I was encouraged though by the message I listened to today about Hope and how since God is who He says He is, our Hope in Him will not disappoint. God rests his promise of Hope on His character and therefore through my hope in the eternal glory of God I know that He will guide me and open doors for me. It is only through Hope in God that we can make sense of our suffering.
