I don't think the people calling for her forced attendance in court understand just how carefully the whole criminal justice process is managed in order to avoid things spiralling into violence and aggression. In the magistrates' court in particular, where there are a lot of defendants with chaotic lives and a low threshold for kicking off, and where there are a lot of cases to get through in a day, judges tend to be surprisingly tolerant of low level bad behaviour. If they jumped on every bit of abusive language, stubbornness, refusal to engage etc, they'd never get anything done - but, more importantly, they'd be cranking up the tension in an environment that already has multiple stress points.
It's rare, for example, for a district judge to have someone sent down for contempt of court - it has to be really high level for them to act on people kicking off in the dock or public gallery. Because they recognise that tensions are high, and winding them tighter makes everything more volatile, and therefore more dangerous, particularly for those who have to take direct action when it all blows up. Everything around handling and detention of prisoners is about de-escalation, keeping things calm etc. If there are heightened tensions around being taken to court, there are more likely to be incidents, as everyone is on edge. It's not just about one person kicking off - one person being manhandled while screaming and shouting can cause all sorts of escalation. It could very easily start with one person dragged into court, and end with a prison riot.
There's also the fact that most court rooms aren't actually that big. The people in the public gallery, the jury, the defendant, the lawyers are all really close to one another. It's one thing to think about it all in the abstract - someone being dragged into court to face justice - and another thing entirely to be right up close to it happening, to hear the struggling and the screaming, and the threats to the judges and lawyers and jury, and the judge raising his voice to try and be heard over it all, and have other people around you getting angry or upset. The whole thing would be brutal and distressing for everyone involved.
