The point is that he is protesting. The point is that this is what protests are about. The point is that he is so desperate that he is on hunger strike again - did you notice the first time?
The point is that staying at home with his daughter, writing polite letters to the government, has made no difference at all. The point is that he is embarrassing the government, or he would be if they had any conscience whatsoever.
The point is not to die. The point is to rise awareness. The point is that he's tried everything else and there's nothing left.
But some people will always miss the point, I suppose.
