Prior to this generation men were allowed to identify as bats. Cultural icon Bruce Wayne was allowed to go around, masquerading as the flying mammal, without repercussion. Everyone agreed they didn't know who the batman was, even though it was obvious to all it was Mr. Wayne. The modern day furry, brony, and people identifying as other animals extend from this moment. You see, in the past upon seeing a person flying, people would exclaim is it a bird, a plane, etc. as if these were not unusual things to identify as. Perhaps the most stunning example is when Caitlyn Jenner was allowed to identify as Bruce and win a men's event at the Olympics. Folks, I have a feeling thats what would happen today if more women chose to compete as transgender men; men would see it as rude to defeat a lady and they'd just win every time.
