Likewise, I do not have as much knowledge on the history of Chinese in Indonesia, not as much as you do and not even as much as my rather rudimentary knowledge of the history of J's in Europe. However, based on my own experiences and observations in the US, I don't see how large scale violence directed towards any single ethnic/cultural group occurring in the US. Sure, the US has seen its own instances of racial violence throughout most of its history, but US society as well as institutions have collectively come to condemn such types of violence and to promote a multicultural and integrated society. Again, racial tensions, inequity, and racist beliefs definitely do still exist in the US, as in most societies. However, to a degree much larger than any other country I am aware of, you still see people of cultures and ethnicities going to the same schools, working in the same professions and jobs, and having the same opportunities as everyone else. And at least based on my personal life's experience, the only times I've felt discrimination or prejudice within the US outside of grade school was from Taiwanese and HKers.
