It's all of a piece.
Woman is a human with female biology. Men are not female. End of.
Except wangle wangle wangle, it's social, it's feels, it's all kinds of bits so men can own it too!
Periods involve bleeding from a uterus. Men don't have them. End of.
Except wangle wangle wangle, men have moods, men have tummy ache, men want chocolate, it's all kinds of bits so men can own it too!
The word 'no' is the real issue here. Unwanted reality.
Talk to a woman with an endometrial ablation. She has all the bits. Fully functioning. But her uterus is currently not shedding. So she does not have periods. Even moody chocolate eating tummy achy ones. She just doesn't. She does not bloody bleed.
But there is no point talking sense and reality to someone with their fingers in their ears with their inner life focused on a delusion.
