Absolutely. Just to piggy back, number one: bigotry is almost always an emotional reaction (facts barely enter into it), and number two: people rarely change their minds in real-time. Instead, they have an interaction (or usually several) and then, very privately and imperceptibly – even to themselves – start to challenge their previous assumptions when no one is looking at their faces.

That’s not to say that facts don’t matter, but if facts aren’t behind your opinion in the first place, challenging them won’t change much.
