“Speech promoting violation of the law may still only be restricted when it poses an imminent danger of unlawful action, where the speaker has the intention to incite such action, and there is the likelihood that this will be the consequence of that speech.” [1]
As others have noted, speech doesn’t have unlimited degrees of freedom in the United States.
The only thing, apparent to me, that clearly protects people from hate speech in America is when that hate speech is intended to cause harm or harm would be the likely outcome of the hate speech.
