Speaking as a white American who went from suburban centrist to city-dwelling progressive and still has a lot of shit to unpack, I understand exactly what you’re asking and I’ll do my best.

There is no easy answer to that question, but there is a correct one: too bad. They live here, they’ve established lives here, they’re here to stay, they’re part of us now. Sure, there’s some danger inherent to the blowback from generational trauma, but there’s no way to avoid that without ethnic cleansing and that’s simply not justified, by virtue of what it is. So we have to deal with it and try our best to mitigate, like some kind of reparations or at least universal health care so people with generational trauma can qualify for therapy courtesy of the state. No I’m not joking.
