VICTOR DAVIS HANSON:  The First–and a Half–Amendment.

Among those who attack free expression the most loudly are progressives who do not like politically incorrect speech that does not further their own agendas. The term “illegal alien,” an exact description of foreign nationals who entered and reside in the United States without legal sanction, is now nearly taboo. The effort to ban the phrase is not because it is hateful or inaccurate, but because it does not euphemistically advance the supposedly noble cause of amnesties and open borders. Of course, the politically correct restrictionists have no compunction about smearing their critics with slurs such as xenophobe, racist, or nativist.

Yep–totalitarians do that sort of thing.
