What's your idea then? Let crony capitalism run amok? Does it make people happy?
The problem is when people who call themselves Left start stirring up a mob into violence, and then more violence, etc. The problem is when people stop caring about issues, and start simply finding issues to help them to victory. The problem is when people start mangling language so that anyone can be attacked for using the language they learned at their mother's knee. I am not talking about the N word, I am talking about basic pronouns - he, she, his, hers. Once you insist on people talking like then people can use it to settle scores. All you have to do is watch enough of your victim on video, pick a few mistakes and call them out.
When I used to go on Nuclear Disarmament demonstrations or demonstrations against the war in Iraq, we were warned to keep everything totally peaceful, and to remember that the police were just doing their jobs - they had no say in these issues. The only physical resistance was passive - lying in the way of vehicles etc (but I didn't feel brave enough to do that).
Some 'witches' had done nothing wrong except irritated a neighbour. Once they were denounced as a witch, the process all too frequently ended in the poor woman's gruesome death. Maybe the instigater had secod thoughts about what they had started - but by then, what could they do?
