I don't understand the desire to assume other people's interpretations are the results of them desiring to interpret things that way rather than having just interpreted them that way naturally.
When I do have a negative interpretation of someone's words, and I'm sure I'm less good at this than I like to imagine myself, I like to think that I at least try to imagine how they would have liked me to interpret those words. This sounds kind of, moral platitude-ish. I don't mean it in that way. Attempting to interpret someone charitably is a self defense. It's for me. I need to think this way to keep myself settled. If I don't, I end up angry at everything.
I think you're right and I appreciate the insight. Thanks.
