If someone is not racist it is not because of some quality of their mind or soul, its because of events that occurred during their life. So it makes sense that if someone's life was different they would have different thoughts

The thing is, people have to actually try and undo some of the damage they did before they can be counted as reformed

Simply being less vociferously racist is the absolute minimum of a start, but it doesn't fix anything

For some though, that's the equivalent of Darth Vader being redeemed by saving Luke and killing the Emperor
