Ask parts of New Jersey. The Indians totally overwhelmed the whites basically taking over their culture by displacing them.
They also housed each other in stacks illegally Latino style. Many played visa games and lied about work credentials to obtain employment. In addition many men harass white women acting overtly lecherous towards them. The whites just gave up and left some towns.
They are also doing so in neo-Asian cities in Canada and Australia. Not because they are they are violent and savage , but cliquish and insular. The main complaint is they lack emotion and individuality. AKA the insect.
At current pace, if the PRC does not reign in foreign real estate investment, much of the Anglosphere cities will be majority Chinese playgrounds and if you believe (((black pigeon)))) possible points of eventual Han separatist movements a la Singapore.
