I don't need to tell you that Pam Noles wins (in every possible sense). Her five part examination of the Golliwogg as a blackface stereotype, and especially in relation to its appearance in Alan Moore's League of Extraordinary Gentlemen, is on her blog and, if you have time, you should read it all:
part 1,
part 2,
part 3,
part 4,
part 5. ETA:
Part 6.
For future reference, this page is worth bookmarking too because it's "well-spoken" enough for ignorant people to be able to understand:
The Golliwog Caricature (from the Jim Crow museum of racist memorabilia).
