Remember the intersexed

"It continues to amaze me - for years now - that the ages-old
phenomenon of persons born intersexed never enters into this "marriage
has always been between a man and a woman" debate. Bull-roar!
Anthropologists, historians, transgenders and intersexed (formerly
"hermaphrodites"): Where are you?! There are statues and paintings
from all over the world since recorded history depicting intersexed,
since they occur in at least 1 in 2,000 births. So I defy any of you
rigid marriage definers to define man versus woman!"
