I partially agree and partially disagree. Racism is a little infectious. You catch it from your parents and local community. It can be cured. The cure is integrating with other groups in a meaningful way, having the space and time to talk to people with different ideas and having a complete psychological clear out. Do those things and you can turn racist people onto a different mental track. Those things take money, they take local governance which prioritises such things. It might be done by the economic left, it won’t be done by the right. :o)
