Sorry, how is this a science related question?

Are you from a major metropolitan area or rural? I ask because a lot of this tends to fester in rural areas and the us has a lot of them. Its not all of it as you also get people pretty quickly blaming when their lives are not great. White people black people, black blaming white people, and citizens blaiming immegrants. Add in that the us wealth disparity is way high. Like it was in the gilded age. We are sitting at a 40 on the index while germany is a 30. Even worse we had a supreme court ruling called citizens united which effectively said money is speech and allows for unlimited money in our politics. Between rich folk wanting to push division among the poor and some foreign influences that really don't care as long as there is division and chaos as maximally as possible. Add in social media and its ability to link up people who locally would be pretty much alone in their views into a nice little confimation communities. Whelp at that point we have what we have today. Its gotten to the point actually were I can't tell how much are assholes are influencing abroad and how much abroad assholes are influencing ours. Alls I do know is the real issue is money and how unbalanced ownership of it is now. the highest is in billions so nine zeroes. So if you don't have at least 5 zeroes you should certainly should know where you stand and because of how massive the increase each zero is. 6 or 7 are still way down closer to the only zero end than the top.

Germany is a top supporter of the genocide in Gaza. What do you mean "we are taught about the Third Reich and never again"?

I’m totally aware that there are still many racist people and even neo Nazis in Germany

This is what you need to focus on

Have you read "Was weiße Menschen nicht über Rassismus hören wollen, aber wissen sollten" by Alice Hasters?

Please. "Vergangenheitsbewältigung" cannot be applied to racism as a whole, neither did it happen in the way that would justify a national mythos (vgl "Gegenwartsbewältigung" by Max Czollek). Please don't point fingers as a European. And German.

Remember that Amerikkka is not a democracy, or socialist country. We are more of a oligarchy and we are ruled by the corporate elite. The system has propaganda everywhere saying we have power. But when the billionaires don't like something they can just throw money at the government (or however they do it) and it will change, Amerikkka is a capatilism country where we brainwash the people that think to believe that not having basic necessities is good for us and instead of helping each other we should fight each other over the little amount the corporate overlords give us.

There will be people who will respond saying "na huh! Not true". Propaganda in this country is EXTREME and sense all media is owned and operated by the billionaires... It's easy to brainwash the country (hence why TikTok is getting banned. Not owned by Amerikkka elites, and word of things they don't want us to know comes out from it, can't control it so ban it)

The difference is that, in World War 2, Germany was reduced to rubble and a significant fraction of its population was killed off because of the direction that its society took. This forced it to take a really long and hard look at itself and figure out what it could do to make sure that this never happened again.

By contrast, the U.S. has never been put in an equivalent position. The bloodiest war in our history was actually the U.S. Civil War in the 1860's over slavery (and some other things, but mostly slavery). Although the anti-slavery North in that war won and was able to successfully end slavery in the entire country, racism itself was a whole separate issue, and (simplifying the history a bit) it continued to exist formally as a less extreme government-backed institution until the mid-20th century. (An example of this were the "separate but equal" schools that segregated black children from white children and were very much not equal.)

Of course, this only changed the law of the land, not hearts and minds. Education is very local, so there is no central authority which makes decisions about these things, and people regardless have the option of sending their children to private (often religious) schools, or even to home-school them. Furthermore, unlike many countries, we take freedom of belief extremely seriously, and additionally we extend this to a near-absolute freedom for parents to teach whatever things they want to their children to believe. The U.S. stance is essentially that we might not like the values that our neighbor is teaching our children, but we like the idea of the government telling us what values we are required to teach to our children even less, and this is essentially because our country was founded on a fundamental distrust of government and this general attitude has propagated down the generations.

So, what would it take for the entire country--and remember that this is a huge and incredibly diverse country--to get together and decide that we really need to, collectively, put aside our own individual opinions of what our values should be and what we should be teaching our children and refashion our entire society around a new collectively held set of values? That is asking a lot of people, so probably the most likely way that would get done is if fascism takes over our country and drives us to start a war that results in the entire country being reduced to rubble and a significant fraction of our population being killed off. This would force us to really take a long and hard look at ourselves and figure out what we could do to make sure that this never happened again.

(Except that now that nuclear weapons exist, "rubble" takes on a new meaning, so that rebuilding part may not get a chance to happen...)

Basically: money 🤑💰. The desire for more of that led to all sorts of bullshit made-up "science" supporting the doing of what the people wanted to do anyway.

Here's a fantastic introduction video from what I consider a great series: https://youtu.be/Ajn9g5Gsv98. In particular it contrasts slavery in North vs. South America, where the latter was so much more violent and bloody and dismembered so many more people that they had to constantly import more bc so exceedingly many died that they could not keep a self sustaining population of them, which somehow still made the northern version all the more evil even while being more "gentle" bc they could therefore breed slaves like cattle.

The dehumanization might have been part of the point, or it may have only been helpful to make the money, but either way, the families of slave owners who did not go out into the fields and therefore were not as closely associated with it - though crucially, still directly benefitted from the work product - went along with it all as collaborators due to the fact that their financial status depended upon them doing exactly that.
