Like most others here, I disagree that any tweets seen here, including "#KillAllWhiteMen, should be considered threatening, and as another noted, her speech would be protected in the US because there is no imminence to her vague threats, aside from possibly that Tory one.
Still, she is probably (assumption) the same type of person to SUPPORT the very law she's being charged with, never expecting they would use it on a poor non-white woman like herself. Reaping what she sowed, so to speak. And that's shamefully pleasurable, I must admit, seeing a racist and sexist bigot get a taste of equality.
