If these people got press coverage, then FLG'd understand. But they never do. It's not news if it happens every single day. Instead, it's a therapeutic activity for the participants. To be completely honest, FLG pretty much feels that way about almost all protesting, but it is especially clear when the person to whom one is trying to address their grievances has no chance of hearing.
If FLG were a dictator he'd keep this in mind. Let people protest. If it happens everyday, then the news doesn't cover it, so no real political harm done. And as far as FLG can tell from the endless stream protesters in front of the White House (or the incessant protests in Paris for that matter) for a lot of people getting outside with a placard and yelling for a few hours about whatever it is that they are upset about is sufficient. They said their piece and go home. No subversive plotting.
