Ideologically we're probably quite aligned. However I disagree with you. Having traveled a lot of the USA, I've found Americans to be surprisingly much less racist than I expected.

Absolutely there are nests of racist snakes, the KKK still continues after all and we have out and out nazis like Nick Fuentes getting page time in the NYTimes, so something is rotten in that country. Even still, compared to my travels throughout Europe, the USA has something unique about its diversity. It does seem like there's something different about the American identity superseding race and religion.

Compare to a country where your statement might be true, insomuch as it's a massive population of practically lost-cause racists: Israel. I've had several conversations with Israelis and my main takeaway is that the government has spent the last couple generations doing its utmost to convince everyone in the country that the planet is a zero-sum ongoing tribal war. The racism there is ingrained not just into the culture but into the law.

Having met people like that, I tempered my aggressively leftist America takes. America has issues but I've encountered way more flagrant and disgusting forms of racism in a year of travels through Europe than I did in decades of travel in the USA. I feel like I didn't know what racism really is until I left the USA.
