Let's not be reactionary and engage with the context of what she's saying. This is exactly the way social tides change. At a first approximation, people develop attitudes when young and retain them until they die (it takes quite a lot of effort to change the mind of an adult, very little to change the mind of a child). If you have some social issue where you can see a generational wave, part of what's going to change the "average" attitude is for the older generation to die off. She's not saying "kill all the old racists" or even "I'd like these people to die". She's saying "our society's average attitude towards race relations is going to shift in [what she thinks is the right direction] as the generation of people who were raised in a time when open racism was the prevailing attitude die off".
