On stupidity and the 2 sexes

I have just watched "The Godfather" the 3rd or 4th time and am wondering why that girl Connie is so stupid. 
From my point of view (probably on account of my upbringing), it's less acceptable for a woman, than a man, to be stupid. 
There are various reasons. For example, women are physically weaker. For example, when an unwanted pregnancy occurs, the girl's the one who has to deal with it, to ask herself whether to tell her parents, whether to give birth to the child or to get an abortion, if not getting an abortion, whether to keep the child or give it up for adoption ... and in some societies there can be more, much more serious consequences for the girl, whereas the guy can get away with it and have no responsibility (as long as she's a consenting adult), at least he hardly has to struggle with it within himself the way a girl does. Etc. 


When a woman lets her husband beat her once, she's stupid level 1. 
After the 1st beating if she lacks the determination to go away but, blinded by love, stays and believes he can change, she's stupid level 2. 
If she lets him beat her the 2nd time, she's stupid level 3.
If she lives with him even when it can be deduced that he's involved in the murder of her brother, she's stupid level 4. 
And after everything she still loves him and worships him, yells at and hates another of her brothers for killing her husband, like Connie does, she's stupid level 5, she's incomprehensibly, extremely, unmeasurably and unacceptably stupid, and there's no more I can say.
