I wouldn't say autistic or that white Americans are all this way. Autistic people are victims of this two faced behavior more than most. Many white Americans are confused by it. That is why so many white Americans drop out of mainstream society to become NEETs or decide to join another society i.e. wannabe blacks, weeaboos, gamers, etc. Mainstream society is confusing and sucks so fk it, just drop out and lie flat.When Americans talk, it's like farting. They have no sense of credibility or responsibility towards what they say and cannot connect thier words to their actions. When I saw Biden's warm open, I immediately started laughing because he is addressing a man whom he once not too long ago, called a "thug." China knows well by now how the US behaves; it's just hard to believe that anyone would shower you with comments of friendship and candidness one day then commit hostile actions against you the next day with nothing gone awry in between. You have to see it for yourself... many times to believe it because it just makes no sense at all. Americans actually don't believe that they are behaving maliciously; American culture is one where two neighbors can be chatting like friends one day and the next day, one recieves a notice from a lawyer that his rosebush has a branch extending 4 inches across the property line. To a Chinese person, if you sue me, I expect it's because we've tried and failed several times to resolve the issue, our friendship is over and it's war between us. To Americans everything is separated and independent of each other and nothing is assumed without contractual obligation (hence, suing someone after an amicable discussion). American interpersonal culture is primitive and quite frankly autistic. Chinese interpersonal culture is highly advanced where every one of a person's actions is connected to the person and thus connected to his other actions in a fluid and coherent web/entity while American interpersonal culture is more like a bunch of scattered random items. While Chinese people are well-versed at making things, even the most uncomfortable things, understood without directly saying them, Americans are still figuring out how to make what one said/did yesterday coherent with what one is saying/doing today.
The reality is, white American society is exhausting to live in. It may have been cool in the 1950s but it aged poorly. They say there's all this freedom but there isn't. While Asian and European children can independently do things at the age of 8 most white American children are under absolute control of their parents in the most basic sense (no freedom of movement without them) until high school.
Then they get conned into taking loans for a university degree that costs tens of thousands and puts them in a deep financial hole starting age 18. Then they graduate to go into a workforce where the average salary is $20 USD/hr... And rent is $1500 USD per month. Then 1/3 of their money gets taken by the government.
Then when they become parents it still sucks. The parents are exhausted because they need to drive their kids around everywhere. Unlike in other countries where kids are independent in all ways but financial at age 12 or so (remember that in the US even walking to school alone or buying at the store is a accomplishment) everything is the responsibility of the parents. In the suburbs high density housing is literally illegal due to zoning. So children never know anyone organically except at school.
End result: children are frustrated, young adults are crushed and parents are exhausted.
