Hitler

Last month,the Chinese Communist Party celebrated its centenary with all the internal fanfare you would expect. The party, which has ruled China since 1949, touted the Twitter congratulations of world leaders from Russia, Pakistan, Kazakhstan, Egypt, Serbia, and elsewhere lauding its record of supposed social, cultural, economic, and environmental progress.

We who have lived in communist countries recognize the signs: American freedom of speech and thought are hanging on by a thread.
