It does IF the people in question have some type of knowledge of the Judea/Christian faith.
I think the lurkers want to know about the ones who HAVEN'T heard.
That seems fairly clear from Romans 1. God "reveals" himself to every man, and then judges that man on the basis of how s/he responds to that knowledge. The universal response of men is to turn away from that knoweldge they have, and thus are guilty. In fact, the scriptural message is that men "suppress" the plain truth about God as He has revealed Himself, because they simply don't like it (Romans 1:19 ff). The question then becomes NOT "how much light does a man have?" buy "how does man respond to the light he has?" The unflattering biblical answer is that we hate what light we have, and prefer the darkness. The judgment on "those who have never heard" is consonant with that. In that respect, the "heathen in Africa" is equal to the "heathen in America." Both get what they want.
