This Sounds Familiar
The claim that Congressman Peter King's hearings on terrorism are a matter of Islamophobia sounds familiar. It makes exactly as much sense as the claim that the prosecution of the Julius and Ethel Rosenberg was motivated by antisemitism.
In other words, the claim does not make sense. These hearings are the new McCarthyism: The opponents are people shouting from the rooftops they're afraid to speak above a whisper.
