Someone that lives in another country isn't necessarily of a different race. If races were defined by country, then you couldn't call discrimination (by Americans of European descent) against African Americans racism as they would be both of the same 'race.'

From the post, it doesn't sound like it stopped him from doing business this time, so that just seems like a very forced segue into the political rant.

And even if he did, that would just be his personal choice, not something the government is actually doing to his business. As I said, it's a tenuous connection. I personally agree with his politics, but until the government actually does something to interfere with his business, I don't see how it's strongly related.
