Haha, it might, but I said that racism hasn't been unlearned by our society. It's possible it seems that society has moved on to you, but ask any black person if racism still exists and they'll assure you that it does (I think we also need to be clear about the differenece between innate bias and racism here, you seem to be conflating the two).

It's not, for the most part, parents teaching their children not to be racist (after all, why would a racist parent even want to do this?). It's children being given the opportunity to see through the fear and ignorance of their parents, because they're growing up in a more dverse society.

90% of bigotry is simple ignorance and the desire for the familiar not to change. But children born into that change aren't threatened by it. Ipso facto, they're less bigoted.
