Nah, let me break the logjam. The only melanin reference litebeam made is
HERE.
Referring to Obama he said:
I don't agree with him, for the most part, but have no objection to Obama being referred to as an eloquent black man, keeping in mind that his mother was white so he might have turned out to be an eloquent white man. If so, would he still have been elected as the first half-black white man? Maybe so, maybe not. Melanin probably helped. I never did ask him what "un-American radical past" Obama had, — 'cause that would really have been informative.
Sorry, in context I don't see a problem, and on reflection I interpreted it that way at the time. In fact, I think he put it in a very literate way.
