I read them the first time round and literally none of them suggested they got locked up simply for chanting. The Tamworth one was the first one where it was acknowledged that she personally wasn’t violent but it’s clear she was part of a group that was and she was actively supporting and encouraging it. If you think that’s just her exercising her right to free speech you’re deluded.
Lots of the other cases mentioned involved no violence but you dismissed them because you didn't understand that you can be convicted of violent disorder without being violent. I'd encourage you to reread them again.
