Plainly you know nothing about China or India, their demographics or history.
The Manchurian-led Qing Dynasty practiced racism that makes Jim Crow look like My Little Pony—ethnic Manchurians had the right of life and death over all other races. It ended in 1912...with an invasion by the Imperial Japanese.
The Mughal Dynasty of Persian Muslims killed 13 million Indians for not abandoning Hinduism. It ended when the British Empire invaded.
Non-Han Chinese and non-Aryan Indians are far bigger minority demographics than anything in the US, and Tamil isn't in the same language-group as Hindi, nor Uighur as Chinese. Spanish might as well be English.
