America may be constantly battling racism and xenophobia internally, but we recognize it for what it is: a shit behavior that should should be excised. European and Eastern cultures like Japan are so casually racist and xenophobic that they don't even recognize it in themselves.

The best way I’ve heard it described is that Americans consider racism something you do, while the rest of the world tends to view it as something you are.

To an American, if someone is a racist, it’s because they do racist things. So Americans are actually fairly good at recognizing and excising casual racism, because they recognize it as a behavior they can change. But this also means Americans are fairly quick to judge individual actions as racist, because they see it as something that should be improved upon in the future. To an American, a racist is racist because they have recognized their own racist behaviors and don’t see them as a problem.

Meanwhile, Europeans and Asians tend to think of racism as something you are. And that’s a big difference, because it makes them much less adept at identifying the more casual forms of racism. Because even if they’re casually racist, they’ll simply tell themselves “well I’m not a racist, therefore my actions weren’t racist.” Since that binary “is/is not a racist” flag hasn’t flipped in their brain, they’re able to tell themselves that their individual actions aren’t racist.

It’s like Europeans need to be at least 51% racist in order to be considered racist, so anything below that amount is excusable. Individual people will obviously have different thresholds for when that Boolean bit gets flipped from “not racist” to “racist”, but it still needs to hit that personal threshold before they’ll start calling out racism. And europeans will tend to judge their own actions much more leniently, like a zealot telling themselves that God is on their side so their bad deeds aren’t really bad.

But that causes interesting culture shocks whenever Americans interact with Europeans or Asians. Europeans are quick to jump on the “all Americans are racist” bandwagon, and the American will tend to nod along and agree because they recognize that everyone has the potential to be racist. Then the American will see the Europeans do/say some vile racist shit, and start to call it out. But then the European gets defensive and adamantly states that they’re not a racist… Because the European takes the “hey that was pretty fucked up and racist, don’tcha think” as a personal “you are a racist” attack, instead of a “that individual action was racist, and you should examine why you did it” behavioral check.

And the American will be confused on why the European immediately jumped all the way to “why are you calling me a racist? I’m not racist” argument. Because in their experience, the only people who immediately jump to that are the full blown reich-wing racists who don’t see their own racist actions as a problem, but want to continue existing in a civilized society. Labeling someone as a racist is a big deal for an American, because it means the person has refused to examine their own racist behaviors, or has done so and sees no problem with the racism. To an American, labeling someone a racist is basically the nuclear “I’ve exhausted all other possibilities, and can only conclude that they’re doing it on purpose” option.

So Americans will often walk away from the interactions thinking “holy fuck those Europeans were really goddamned racist” simply because the Europeans refused to acknowledge that their own individual actions had the potential to be racist. Meanwhile, the Europeans will think that Americans are really fucking racist because Americans are quick to call it out amongst themselves.

It’s also about fusing different cuisines together, to make something new. America is the big melting pot, and that means you end up getting flavor palettes that otherwise wouldn’t have been brought together.

Traditional Mexican food isn’t anywhere near as spicy or as cheesy as Tex-mex, for instance. That’s because Texans took the traditional Mexican cuisine, combined it with American peppers and English+North American aged orange cheeses, and created Tex-mex. Tex-mex also tends to rely on flour instead of corn, because Mexico had red/yellow/white maize (and later, modern yellow corn) while American settlers had wheat.

And then California Mexican food is an entirely different third type of food.

Hell, my favorite local pizza joint sells a chicken tikka masala pizza that is fucking wonderful. We have a really big North Indian population in my area, so lots of the local restaurants have veggie options (India is largely vegetarian) and/or Indian spice blends incorporated into some of their menu items.
