Regarding the picture of the messages on the door: All of the pieces of paper are the same, all of the tape used is the same, and it looks like the same marker might have been used on those signs. I can't go back to look at the hardwriting because of the paywall. Theory: one person made multiple signs. Regardless of the signs: At what point should a group of people dictate things for other people? Is it via # of people, % of people, position of people, the differentiating possibilities are endless. Should a line be drawn, if so, how do we determine where the line should be drawn, how do we determine if something crosses that line?
