Who fucking cares? The PATRIOT Act was in response to the worst terrorist attack on US soil in US history. Three thousand people. I have friends who were in New York then. The Japanese internment camps were in response to Pearl Harbor. If an action is wrong, the impetus doesn't fucking matter, the action is still wrong.
6-4 (Tiananmen) was not ethnic violence, do we agree on that? And the Chinese government does use internet censorship to suppress discussion of it, are you going to deny that?
