I would include each other's countries as well. It can be difficult but I always try to separate what I may think about a country's government from the country and it's people despite the fact that we all tend to write about "country" when it's more accurate to say we mean the state, the government, or it's policies. My country as an example, may be at odds with Iran most of the time, but I have absolutely no ill feelings about Iran or the Iranian people; to the contrary. The same goes with me for Russia, China, etc.
It's one thing to have an honest criticism of a country's policies. It's another to insult a poster's country for the purpose of enraging people or just to be insulting.
