She incited people to set fire to hotels on July 29th and that?s exactly what they did on August 4th. Of course she was dangerous, demonstrably so. Her bereavement was taken into account when sentencing was passed as mentioned in this very good explanation of her case here;

She pleaded guilty to an offence that carries a maximum sentence of 7 years. Previous racist messages on her WhatsApp were also taken into account as was her failure to post any messages of sympathy for the Southport victims.
I do wonder whether you and others would be so concerned about this sentence if the person involved was a Muslim and they were inciting rioters to set fire to a hotel full of white people. Throw away the key might be the more common sentiment.
