We had slavery, which even when that was abolished still had Jim Crow laws that segregated people, and even after that we still had degrees of apprehension which led to the self destructive gangland culture. We killed tens of thousands of Native Americans. We interned thousands of Japanese during WW2. There's probably a big anti Hispanic thing I too but I can't think of any off the top of my head, Spanish American war maybe. And America is majority white.
Now it's gotten a LOT better over the years but only recently has it been turned into the mess it is because marxist are trying to supplant commie ideology into the youth by bringing these facts up along with general Right v Left politics where any criticism of the Left is seen as racism (among other isms).
Tl'dr, White people had a history of it and currently because Marism is making anything right of 'Replace White People with minorities' as Alt Right extremism.
Hope that helps.
Oh and as for your first bit that's because the three major Asian nations have fought each other and themselves more times than people can count.
