This is an absurdity that is almost uniquely American.

While I hate the "love it or leave" mentality, this statement is ludicrous. Hyper-nationalism exists everywhere. You mentioned France. There is a huge right-wing nationalist movement in France, but they don't want people to leave who disagree with policy, they want people to leave who aren't ethnically French.

Nationalist movements are rampant in Europe, where the recent influx of immigrants have changed the social nature of the various countries. As for Japan, there may not exist in this world a culture more xenophobic and resistant to outsiders.

Hate to break it to you, but there are a$$holes all over the world.
