I don't see anything that indicates these values should be opposed. I've seen controversy over this before and to be honest it mostly seems to be people projecting their own idea of what the left thinks - that "white values" implies they are not "black values" and that all whiteness = bad. Then they conclude from a decent summary of dominant values in America something like /r/conservative's take: "#DefundSmithsonian ... We are paying for white genocide with our tax dollars."
