you can have some old geezer who has said racist things his whole life, but if a black bloke moves in next door and he starts to become mates with him, he'll become less racist without ever admitting it. he'll likely still say all the same shit, but his heart will have shifted.
by the same measure you can have the most liberal and open minded person who spends a lot of time calling out racism who gets rumbled by some black kids in a dodgy neighborhood for their phone. they'll continue to say all the right things, but will start looking over their shoulder whenever they're out on a quiet street and someone with a bit more melanin in the pigment is hanging about.
