The fact of fleeing, requires first the fact of belonging somewhere, because you can't flee if you don't belong somewhere first. I will explain myself. If a house that is not yours begins to burn, and you leave, it is not flee, since you do not belong there, on the contrary, if your house is burned, and your family is there in the fire and you leave, then you are fleeing, because you are not doing anything to prevent your house from getting damaged.
So the answer is simple, if you leave the place you belong by external imposition, then you are fleeing, and it is unworthy, because you are leaving your family and your friends in pain. If on the contrary you go from a place to which you do not belong, then you are not fleeing, because you simply do not belong there. Having answered that, it should be noted that there is no honorable escape, that is, you can not leave the country and make an external struggle, the national problems must always resolve within the border of the nation, without foreign intervention.
In the examples I put, people never left their country, because North Korea and South Korea are not two countries; East Germany and West Germany are not two countries; and China, Taiwan, Hong Kong and Macao are not four countries. All these are one country, but they have two or more States, so the people who move from one place to another are not leaving their country at any time.
Help me understand you. You propose that if a person, say, with a Chinese passport feels so unhappy about the politics of his country as not to belong in his country though wants to belong, he may state this politically by becoming a resident of Hong Kong or Macao or a citizen of Taiwan?
Yes.
