I know basically nothing about any of those countries other than having vacationed in Mexico twice. I haven’t seen anyone say they are fed up with the U.S. and moving to Paraguay.
Note: Mexicans have been emigrating out of USA for about a full decade now.
So statistically speaking, Mexicans have been saying they're tired of USA and have moved back to Mexico.
Unless the Supreme Court is about to make some sweeping changes to "State Rights", good luck to them fucking over state prosecutors and state legal systems.
The Court of Delaware continues to be in control of Twitter (and other corporate cases), not the Supreme Court. The Court of New York remains in control of Donald Trump's felonies. Etc. etc. Sanctuary cities (and sanctuary states) will likely be able to thumb their noses at ICE (a Federal Agency with little power over the local state's residents).
State-level resistance is the next step. I know not everyone can move to a Blue State, and a lot of this is Red States purposefully purging "undesirables" out of their state. But... Blue States can accept the runaway migrants and protect them. As well as a lot of the other citizens who feel threatened (ex: LGBT and whatnot as well).
Will it completely hold? I dunno. But its the next bulwark we have available, and we might as well defend it as a community.
