The "previous pastor" in the Snopes question is amazingly supersensitive--and ignorant.

Even beyond the the question of buck as being racist --which as Snopes says is hogwash--even the term "young buck" is also not racist.   

Lots of whites use it--on themselves.    Gamble Rogers, for instance, says of his childhood in one of his stories::    "We were just young bucks-- boys growing up."

That quote from Scopes needs to be emblazoned on the foreheads of some Mudcatters--the one about "As fashionable as it is now" to see racism in all sorts of words "as if we could erase our history by eliminating some words from our vocabulary", that's absurd.
