As a UK subject, with a government that has begun implementing the online safety act, prosecuting people for tweets that clearly weren't inciting violence and getting rid of jury trials for cases with fewer than five years sentences, I look on with envy at your constitutional protections of the individual.
I should be clearer and provide references etc, I was refering to this: https://freespeechunion.org/labour-reported-me-for-racial-ha...
The major part of this case is that without a jury trial he'd probably have had zero chance of being cleared. Countless others were persuaded to plead guilty to avoid a long time in prison and then were given long sentences. h he was strong enough not to give in.
You are right, freedom of expression in the US doesn't cover inciting violence, but it has an high bar, imminent lawless action:

Yes in Lucy Connolly's case she admitted to inciting violence, though I'm not certain what she did justifies a 31 month sentence.
The problem interpreting the intent of that tweet is that Lucy Connolly herself admitted to authorities she was inciting violence so becomes hard to build a defence at that point. Incitement isn’t first amendment protected in the US either https://codes.findlaw.com/us/title-18-crimes-and-criminal-pr...
