Adding further thoughts on why it rarely helps. Say, I do convince another person that they are racist, and should change. they are likely part of a family that has racism issues, and they probably have friends that are racist. How many people are going to be willing to then come out against those people, at the risk of those relationships?
Sadly, far too few. Similarly as many allow themselves to be forced into having kids, even though they may not want to, and definitely shouldn’t. Edit: the problem is that it is so systemic, just like generational traumas.
for neurotypical people, perhaps. many of us on the spectrum are fully capable of changing our minds when presented with logical arguments, facts, and data. hence our frustration when we can’t do the same with others.
