I understand what you're saying here, but I think you've got it backwards, even taking PyCon into account. I think we both agree that it's best to assume everybody is acting in good faith (you say as much in your proposed changes). As such, why not: "Despite these rough guidelines, we are all imperfect human beings that experience discrimination and offensive language in sometimes drastically different ways so it's important to be aware that you might say something with good intentions that nevertheless offends or upsets another member of the community. In these cases, rather than explaining to that person why they ought not be upset, apologize, try to understand why your comment upset them, and move on."
