for some yes. plenty of social issues involving race. though its often difficult that implicit bias isnt impacting many things. some folks dont like the 43 president or jim tressel since they are devote and open about their religion. some people do not like the 44 president, or tiger woods, or lebron james do their pigmentation. i think though when it becomes common parlance, rather than based in more reality in those situations (as listed above-political reasons, adultery issues, moving teams via a pr stunt, or generally thousands of other reasons that significantly outweigh the race/religion/discriminatory trait).
to say race issues do not exist is purely a fabrication, to assume that any outcome is purely based upon race when other, and often obvious factors play a huge part. simply stated many people have come to despise favre not b/c hes a giant hillbilly, rather for his pr driven antics. i think the same reality has caught up with lebron james. and im sure, id bet a lot that some people didnt like lebron before, or after his choice based purely upon his race, though that number dwarfs the people who have cooled on lebron b/c of his stunts, antics, and pr debacles...
