answer:Sure. Non-violent communication, and not collapsing individual events with labels. You’re already pretty clear about things like not rushing to judgment (e.g. realizing that people may see the stereotype as an occasion to dump their own rubbish or frame them, for example, is a real possibility) and so on, so you sound like someone who might be willing and well-suited to doing the communication. So, it would look like talking to them, and possibly talking to various local figures, about their needs and the static community’s needs so both sides understand clearly and can see solutions that work for everyone. For support, tips, info, etc, see for example the Center for Nonviolent Communication and I would highly recommend (to everyone, actually) the short book Nonviolent Communication: A Language of Compassion by Marshall Rosenberg.
