These are a sample of the personal pronoun preferences I have encountered, plus the implied binary opposite for the relevant entries. They are ranked roughly in decreasing order of frequency with which I encounter people willing and able to honor them, and to punish others for failing to honor or at least try to. Everyone is ok with #0, most liberal/progressive people are ok with #1 and increasingly often #2, things get fuzzy past that, and nobody is ok with #9. Of course most people draw a line in the "only" "reasonable" "obvious" "respectful" place in between and consider discussion of where those lines are to be extremely disrespectful.
