I don’t trust people’s ability to behave virtuously. And by the way, I explicitly stated that the hypothetical non-racist was no fighting racism, just that he wasn’t specifically racist.
True about your hypothetical, but I think a baseline of non-racism in one’s daily dealings with others has power, if not counting as “fighting.” And if you get a lot of people to not be racist in their personal dealings - say the same number of people who advocate for a given law - then that would be really powerful.
