It was a simple question, cool your jets. I also don't think it's unreasonable to expect a US citizen to know the 1A'a broad coutures.No I'm not genius. Why don't you explain this landmark case to me instead of being a patronizing douche.
It's the Supreme Court case that established the standard for imminent lawless action, and its been reputedly upheld. Speech calling for violence is unprotected only if it is in imminent danger of causing lawless activity.
To give an example of how high that threshold is, the Supreme Court latee held that burning a cross on the lawn of a black family is in of itself protected speech, unless there is intent to intimidate.
