New Preamble To The Constitution

[Hobbit]

I'm sure many Yankees, circa 1860, would have approved of a similar measure.

And they were correct, too. Expressing sympathy towards an enemy or disapproving of action against them is one thing, inciting violence is another. If I say, "We should leave the Middle East immediately, because the Muslims need to be left to rule themselves," it's protected. If I say, "For the good of the world, we need to rise up and attack the American government, killing its agents and destroying its buildings," I would expect to be arrested.
