When Donald Trump was threatening to win the Republican nomination for president, it spawned the response of some people saying that if he won, they would leave America, and the usual destination mentioned is Canada. Now that he has won the nomination, the threats to leave if he wins the presidency can be expected to increase.
Such threats are not new. I have lived long enough in the US to remember similar threats to leave if other candidates won, such as Richard Nixon and Ronald Reagan and George W. Bush. These threats tend to mostly come from fearful liberals about the prospect of Republicans winning and not the other way around, maybe because conservatives tend to see the rest of the world as hideous and dangerous dumps full of anti-American sentiment and that they are always better off here.
But the very fact that Americans feel that they have the freedom to go to another country merely if they choose to do so highlights how privileged they are. As we see with the refugee crisis, for most people leaving one’s own country and being accepted, let alone welcomed, by another is a real luxury and often requires making a strong case.
