For example:
From his website, "An open society is a society based on the recognition that nobody has a monopoly on the truth,"
From the interview, "the Republicans are much better at messaging and distorting the truth."
Apparently liberals have a monopoly on undistorted truth.
Those who tell the truth have a monopoly on the truth. Those that live in a lie are left out. Sorry, Georgy Porgy.
Karl Popper defined an "open society" simply as one in which political change can happen without bloodshed or a coup d'etat. Of course this definition doesn't allow Soros to take a subtle swipe at his ideological opponents.
