Not the majority, but a non-trivial minority? Absolutely.
Even if a majority does not actively seek to oppress blacks, wide swaths of becausmerica persistently oppose remedies intended to mainstream blacks (e.g, affirmative action), vilify efforts to make society more inclusive (e.g., dismissing such efforts as politically correct), oppose policies to create more equitable economic outcomes (they're socialist, after all), continue to vote bigots into office, engage in pervasive negative stereotyping of blacks (e.g., our very own Carolina Jazz), and so forth. So, while not actively and consciously seeking to keep black people oppressed, many, many whites continue to oppose just about every approach conceived to remedy the results of past oppressions, while clinging to comforting myths, such as the rugged American pulling him/herself up by bootstraps, merit and hard work ensure success, race is a non-issue, policies designed to benefit the entrenched economic elites actually benefit all of society, etc.
