@AnarchistArt I respectfully disagree. I think in certain rare instances it can work. The two famous examples in regards to racism are: a) Ann Atwater who befriended C.P. Ellis b) Daryl Davis who befriended Roger Kelly. At least in those two examples, both members of the KKK eventually changed their minds and quit the organisation.
I'm not claiming that this is a strategy that will always work or should always be pursued, but what I am saying is that it's possible to change people's minds.
