A suggestion regarding the earlier ask about debating with 'two gender' folks: Remember in kindergarten when there were only ten numbers? When there was only up and down? When people were either parents or kids? It wasn't long before we discovered fractions, and figured out that some people were weird things called teenagers. Nothing in our lives stayed binary for long. When we look back it seems like very childish thinking, even though it made the universe easier to understand at the time.
This is a really interesting and (I think) good analogy. Thank you.
