People like to say that "You can't change people's minds with data!" That's kind of true, but not really. You can definitely get some folk to change their position on topics with data. You can't get other folk to stop being racist/sexist, etc with data, because racism/sexism etc are lies, and the person got themselves into that situation specifically by rejecting the truth.
But good news, not everyone is racist/sexist because they reject the truth. Some people have had the truth kept from them.
