If we could simply cure people of ignorance, then yes, we could make the whole problem disappear without any messy policymaking. That would be wonderful; it also strikes me as very unrealistic.
As I've said many times to usually be ignored, I don't care to try to eliminate racism, because as a policy goal that makes no sense. However, I do care to mitigate the negative effects of prejudice. Perhaps that would be a more effective framing of the problem, but I've also made it clear that I don't view sparing people's feelings by avoiding loaded terms as worthwhile, either.
