No. people don't need to fully assimilate. Culture isn't convergent, it's divergent. What is American? Bratwurst? Spaghetti? Pad Thai? Muck tuck? Corn? Yep. All of the above. You've got shutters covering some real beauty. Hmong people I've worked with have been open, generous, intelligent, and highly emotionally intelligent. People celebrate their vibrant culture that they barely survived with and you bristle with hate. Sick.
