I do not want someone to come to the US just to push for dramatic changes. Sorry, but you can do that where you already are.
Obviously someone who is 80% positive and 20% "here are some improvements" is one thing, but if they spend all their time whining about US imperialism, I do not want them.
Not great myself. Sometimes you move someplace specifically to assimilate with the culture because you feel it's a leg up from where you left. When it is infuriating is when someone comes from someplace that has been torched by failed ideas, or at least failed in the sense it drove them to leave, and they set up shop and do the same damn thing. It ought not be illegal, but for instance you see that with home owners that flee and then vote for the same dumbass stuff that made their origin unaffordable.
You have the right to just show up with newly printed residency and demand change, but no right to be liked for it.
