Along these lines, I found myself thinking about how some try to distinguish non-binary identity from trans identity using those imaginary points, and it just ends up pointing back to siblings.
I've given a lot of that a lot of thought too. Sometimes I wonder if I'm starting from the position I want (total acceptance) and working backwards but I then remember that I started from a different position (anxiety, distrust) a very long time ago to get to THAT position using my same work.
