Mood swings read as instability/risk, not depth.

This baffles me, how could any self aware person who has thought about it at all not realize this?

I thought the only reasons this was done were because

A) Some women genuinely couldn't control themselves. (PMDD, I've had uncut female dogs, they definitely can have uncontrollable moodswings, I have heard horses are the same. Cats are completely different.)

B) They know they can get away with it and it is fun. (Anthropological culturally linked dissociative disorder PMS, basically women mimicking PMDD whether they are aware or unaware of doing it)
