Seriously, the idiocy is hilarious. It's not rooted in the black slang "brother." I mean for crying out loud, at least in the North and West (I know down South it's a bit different), blacks do not say the word. Neither do Nords say it either. The term, according to one of the answers in that link originated in England, when an Archbishop of the Anglican Church wanted to shorten the term to make it personal. So English folks started using the term to each other. I think the Italians and Spanish made it a greeting. Blacks have no history with the word. Neither do Nords.
