It's human nature to prefer what is similar to yourself. We see that trait exhibited in many many forms in human behavior. Managers and Leaders react more favorably to employees/people similar to themselves for example. Most people are more attracted or prefer to date people within their own race. I'm just not sure you can eradicate these natural preferences. Pure bloods could almost certainly become the minority though. Or mexicans could just out breed us allHAHA.
Tell that to their great, great grandchildren.
It's ridiculous.
Racism WILL be faded out.
