The thing is, white people generally aren't the type to speak out of racism. Generally whites don't care. White people response to this proves it. For example a video of Ray Nagin
If Ray Nagin was white and said New Orleans is a vanilla city and he "don'â„¢t care what people are saying uptown or wherever they are, this city will be vanilla at the end of the day" he definitely would be forced to resign and the response would be big.
If white people made more efforts about racism toward them and spoke out against it things could possibly change. Like I said earlier white people don't care generally or feel that they can only be racist.
To make a change you have to speak out against it.
