U.S. Political Forum: Goofy reasoning.
You're confusing symbolic speech with private speech. The Court treats them differently.
As for the 909's OP, the Court is essentially treating the girlfriend's statements the same as they would treat an anarchist or Commie's speech when they try to incite a riot.
Hate to break it to you but incitements to riot are not protected free speech. Nor are encouragemnts for suicide.
And that's the correct, Conservative Constitutional decision. Scalia would approve.
