I have no dog in this particular argument, except to say I don't think the two things (Larkin's status and the presence of a White Hope undercurrent) are necessarily contradictory. For one, it may be different factions of the population espousing the particular views, but beyond that, I don't think it's hard to envision a person attached to the team enough to cheer the team's black stars, while the fact that he finds himself in that position making him even more resentful as a white dead-ender.
