I balk at the thought that someone would even consider you transphobic or a bigot, as you are neither. Intolerant of ignorance, sure, but not of people.

I have seen the "no unpartnered men allowed" rule at exactly one event, and I don't believe it ran again after that. In any case, it torqued my gears quite a bit that there was social exclusivity at an event that was supposed to be open to all.
