Yea, well you were not kept as slaves, killed for learning to read, beaten with inch and a quarter thick poles (often to death). Your families were not sold separately to different owners and broken up. You were not systematically excluded from education, jobs, housing, medical care for generations and eveb lynched for generations.
Never heard of coolie labor, have you. In much of the Americas, it was literal slavery, and in the US, it was slavery in all but name. Until 1879, where it was recognized as slavery even in name, in the constitution of the State of California.
Asiatic coolieism is a form of human slavery, and is forever prohibited in this State, and all contracts for coolie labour shall be void.
Chinese immigration to the US up to that time was nominally voluntary. And you can believe as much of that as you like. Once they got here, they were enslaved with contracts of indenture that were rigged to be impossible to pay off because they were forced to buy all necessities from the company store, which was rigged to make them go further into debt. It didn't last nearly as long as Black slavery, but it still involved hundreds of thousands of enslaved people. Many, many third and fourth generation Chinese-Americans can claim a slave ancestor.
They don't. And they don't dwell on it.
