as an invisible old woman, i sort of have the opposite situation, but really, the same. i am the daughter of the witches their ancestors couldnt burn.
yes, a natural part of the human species. i put a lot of stock in the idea of evolutionary psychology (misused as it has been.) if we can have drone bees, we can have members of the tribe not actively involved in reproduction, or outside monogamous relationships. built in foster parents are a great thing in a tribe, as are those who have more energy for artistic pursuits, because they are not weighted down by offspring, especially gangs of offspring.
in college i was taught about native tribes that honored those w 2 spirits. this has to be a thing.
i think us humans come in several flavors, even outside gender and sex. i have a kid i think is a natural warrior. another that i think is sort of a natural hermit (read- natural sperm bank). and artists all over in the family tree. genetically weird everywhere.
and you are right, suppression has always failed in the end. many around here have been in the battle for a long time. she has a web wrapped around her that she doesnt even see.
if i have anything to say about it, she will endure.
