An example is the Vietnamese fighting the French and Americans. They wanted the foreigners out, and a society governed by indigenous people. The Vietnam war was a race war from the Vietnamese viewpoint, and a powerful motivating force to rally their armies.
You keep using those bad analogies, which make it look as if the US is under attack by hordes of Mexicans and Koreans and Indians and Russians. The Viet Minh objected to colonization, not immigration. It’s true that the experience of colonization, plus the Viet Minh’s own extremism, created a racially intolerant atmosphere, but that’s not a feature but a bug, which caused Ho Chi Minh to slaughter hundreds of thousands of Cambodians. Luckily, the Minutemen haven’t gotten that far yet, but that’s only because they live in a sovereign state that has a monopoly on the use of force and so far doesn’t think mass murder is good policy.
My personal experience is that Americans as an ethnic group are one of the most tolerant and inclusive in aggregate.
That’s been my experience too, but it’s precisely because Americans are likelier to tell people who rant about foreigners to get lost than other people. Japan is one of the most racist societies in the first world, with rampant discrimination against Chinese and Koreans. Germany, which only recently began giving citizenship to third-generation Turkish-Germans, is almost as bad. In contrast, Americans are likelier not to care which identities people assume, and to seriously fight discrimination. Due to slavery and segregation, they’re also likelier not to be hubristic about their racial tolerance. Aggressively promoting assimilation or ranting about the dream of border controls or downplaying its own racism will just turn the US into another Japan.
My ancestors were here before there was a Germany, Italy, Israel, India or Pakistan.
Not unless you’re a native American. The current incarnations of Germany, Italy, Israel, and India are relatively recent, but all of those countries are millennia old. Pakistan, a creation of Hindu-Muslim tension in early 20th century British India, is the only one of the five that didn’t exist 2,000 years ago.
