“What does that mean?”
Writers could not make stories about paranoia of communism.
But they could make stories about aliens and make the same point.

I think that Nolan and his writers are doing the same thing with the war on terror with Batman.
The only problem is, it wasn't paranoia. There WERE Communists collaborating with the Soviet Union in the State Department, in the Defense Department, in the highest levels of the Truman and Eisenhower administrations, and in Hollywood.
Cold War era documents have proven beyond any doubt that McCarthy was right.
Conservatives should never go along with the lie that concerns about communism were paranoia.
