That's a tautology. If I support freedom of expression, and believe it is in the say, national interest, then by definition I am against those who oppose freedom of expression. Where the line ends is when they stop merely saying "we are against freedom of expression" and actually harm people expressing themselves. We've definitely crossed that.
