> Although you seem to make you case a bit too extremely, as having two or three children doesn't entirely destroy free time and social life
I described what experience of having one or two children is. All those are real effects on women and if they trust you a little, they openly talk about them.
> nor makes her powerless in case of abusive relationships.
Specifically, yes, it makes you a lot more vulnerable. You are now forever tied to the dad, you have harder time to keep good job (so more dependent financially) and yes, the abuse tend to escalate.
> in fact you have just described a woman with children as isolated, with reduced social skills, boring, helpless in the face of abuse.
Yes that is the worry. The social isolation is very real and painful. The reduction on social skills is observed phenomenon and something openly talked about. And more helplessness is one of the consequences of having children (especially if with wrong person).
> Can you name a socially positive trait you attribute to a mother that is dedicated to growing her children?
I did not said THEY are bad. I said these are impacts and consequences of being mother dedicated to growing her children. So, the positive trait is that they suffer the above for the sake of kids. You are the one implicitly blaming them for natural consequences of the situation.
> And otherwise, why would anyone take such a burden?
Fertility is going down.
