Sparky, you posted your stream of consciousness as I was catching up on the thread and formulating my own!
I was thinking (fragmentally):
I was born into a family that devalued women,
but also relied on us -
leading me to develop an 'othered' identity, or to put it differently,
to live in the 'grey area' described above.
So I find the 'behind enemy lines' idea easy to understand.
Because of this problematic personal legacy, I'm interested in how/why this happens -
and agree with sieglinde that it's not logical.
No benefits in 'binary' thinking, as LRD points out!
Good points made about infrequent menses: we're always being told it's not 'normal' to have a period every month.
I haven't experienced disgust at menstruation, sakura, despite having the kind of periods that unpredictably drench my surroundings with blood - sad that you have found this, but not a universal experience.
Going back to superstition, women do have power over life & death - from a superstitious pov, very mysteriously so.
Not only do we bleed, but we get pregnant and then lose the baby - after which we bleed like a dying warrior, but don't die. And we can die while giving life.
That's some scary force.
It's idiotic to discount superstition as (the strongest) defining force in our societies.
You only have to travel a couple of hours - to Romania, for example - to find a societies still dominated by magic and ritual.
Superstition was - and, largely, still is - mankind's attempt to 'control' and make safe an incomprehensible, dangerous world.
Umm, I may have to another one of these later
Sorry!
