I know someone who left back in 2018 because of all this. It's not new and it's not going away or getting better. The woman I knew who left, had concerns we have on this board, which were deemed unacceptable.
They were happy for her to set up and man stalls, hand out leaflets, do all the donkey work though...strangely, she wasn't quite so happy to be everyone's bag carrier while also being ignored and silenced, so she left.
