“In some ways it’s like occupied territory, customs from the old country valued very very highly.”
This is the problem in a nutshell. If these immigrants - any legal immigrants really - came here and wanted to be Americans things would be fine. If they want to come here to live IN America but with the attitudes and customs that turned their former countries into crapholes, it will never work. Well, if the goal is “balkanize America” then it will work. Because that’s exactly what’s going to happen.
That’s my take also.
