I don't know how the US goes~

But I know quite clearly that in China, the government close many numbers of
nationalists website. Few website can survive ,and one who, survive ,is now being strictly watched! And most of these website are built by personal.

It seens that China want "harmonious world"outside ,and "harmonious society" inside. It really do much effort. Though some people have less freedom to share their nationalists viewpoint.
