Racism and bigotry are not exclusive to one people and/or race and to make the statement Oprah made just proves my point. You also don't stop racism by more racism but people are flawed and failure to call out racism for what it is or failure to acknowledge it as being found in all races just advances it.
I know many are not religious but being religious I want to say until we approach each other and look at each other as God looks at us we will always treat each other differently.
God looks at all of us as the spirit/soul that He created rather than the outer flesh. The spirit/soul had no gender nor does the spirit/soul have color or any other physical thing. Until we can approach each other that way then we will allow our bias and prejudices to affect us.
People will always be different in the physical ways but our spirits, that eternal spirit/soul is the same for all mankind and the way we defeat racism and bias. At least that's my opinion. Oprah should consider her own failings and racism/bias before judging everyone else. The easiest way to grow and advance racism is to ignore it or worse fail to recognize it.
