In my reading of the postings, it is not important to Marcie's position whether only a single person is upset or larger numbers of people are upset. All it takes is a single person waiting one night with a knife or a gun to get you an extended visit to the hospital or morgue. Therefore (in my reading of the posts), if even one person dislikes what is happening, Marcie recommends either dropping back to (public) normality (to remove the chance that the other party might freak out) -- or to make one's will and be prepared for the possibility of dying for one's earrings. Dealing with the situation through HR or a peace bond or similar is not recommended in Marcie's view, as that might trigger resentment and violence. In this world-view I gather that one should either hide oneself or prepare for the day that will come (not might come) of being physically attacked.
Of course, this position does neglect the point that what has set off some people is that the people around them "are all just sheep", blindly following everyone else, and since the role of sheep in the food chain is to be slaughtered, killing a bunch of "sheep" is no moral problem, or is perhaps even a "moral good" as it might "wake up" some people. Thus hiding behind normality is no fail-safe either.
Presumably Marcie follows some recipe of behaviour that leaves her safe from attack by crazies, including ones upset that (say) she didn't hold the door open for them -- or upset that she did hold the door open for them ("Are you implying that I am weak, that I can't get the door for myself?!" ), but, Alas, my imagination does not reveal to me what that recipe might be.
