Actually, most black Jamaicans and other islanders trace their roots back to Africa. Dark skinned Arabs or South Americans, however, usually do not.

It's funny how a white person is racist if they call a black person "a" black, but no one even bats an eye when black people refer to whites as "whites." I would say the same about words that are perceived as gender specific. When I say "mail carrier" in place of postman, I feel like I am also saying, "I understand that there may be women that are offended by my use of the word "man" when referring to them, so I will use this gender ambiguous term instead."
Maybe we should just stop being emotional about it and focus on actual injustice instead of trying to turn ignorance into injustice.

I think this goes right along with improper uses of "your" and "there." It boils down to laziness of children in school. Just look at the terrible grammar used in some graffiti.
Also, words like thee and thou are no longer common in English usage. I believe that English will continue to morph along with societal demographics. If you don't like it, welcome to Earth.

In many parts of England, people pronounce "th" as "v" (brother=brovah). Also, "all of a sudden" when spoken quickly, sounds like "all va sudden." So, the English bastardization makes sense.
Language morphs over time, usually due to laziness. So, like it or not, "all the sudden" is likely to replace "all of a sudden" because it is slightly easier to say.
I could point the prevalence of "all the sudden" in southern states as evidence of this, but that might be perceived as a jab at their litteracy or work ethic, so I will refrain.
