I’m not downplaying its existence but its wider social effects. If a society of two thousand people is racist against two members of that society, that is not likely to affect the mental health of dozens of members of the society - at most only those two who are the direct victims and those who are close to them.
To add to my other comment, I noticed I failed to address this earlier comment of yours: https://kbin.social/m/[email protected]/t/954121/-/comment/6137667
Here you do exactly what Haidt criticises, IMO entirely correctly - focusing only and exclusively on the situation in the USA. Which absolutely looks narrow and reductonist.
