Color Blindness

I saw an informal study done on the news a few years ago about who landlords would rent apartments to.  The researchers had people of different backgrounds call the landlord over the phone using different dialects and accents and had them say and ask the same things.  When the people called using the African American dialect and a Mexican accent the landlords would tell them that the living space was no longer available.
Whether or not the landlords were aware of what they were doing, racism was obviously at work.  I could not agree more with Bonilla-Silva that Colorblind Racism is an issue and is more detrimental than helpful. Racism is and issue and ignoring any issue it not good.  Most people would agree that ignoring an issue is not a good idea and could only make things worse.  So why does society ignore racism? I know that we want to believe that we are past this but I think everyone could think so something that would show that racism still exists.  I wonder if we made society more aware of the issues still prevalent that we could work together towards improving them or if racism is something that society will never be able to rid of and colorblind racism is just a coping mechanism.
