Could counter-demonstrations seem to overly back the odd legal system and the rule of law? They might seem to position the left as defenders of how contempt of court works in its details. Which may well be better than seeming to back the defendants in the trial that TR was 'reporting' but it's still an odd place for the left to be.
Too nuanced for me to explain properly, I'm afraid:
I'm all for denying the streets to fascists but clarifying that while one is 'against' them on a broad principle, one is not 'for' what they're 'against' on this occasion, at least not in the specifics of how TR was banged up on a judge's say-so, but yes on how he prejudiced a fair trial for his own ends. He should have been tried, found guilty by jury if possible and sentenced, which would have been more difficult for the fash to have a go at. The apparent martyrdom of someone locked up without a court process for 'free speech' plays right into their hands.
