I don't know any mothers like the woman who wrote this article. Like you said, she just takes selfishness to a whole new realm.
Alas, I have known some like this.........
Count yourself lucky. Wife's friends and family are liberal to flaming feminist and I get to hear this tripe all the time. No idea what she has in common with them.
Some of her friends are pretty good Moms, but the ones that stick out, really stick out. My wife is a stay at home Mom, and I think that they simultaneously envy her, while they're guilty for their own selfishness of not being willing to make the sacrifices needed to stay at home. (Please note - they're ABLE to stay at home, all married, husbands have stable jobs, etc....they're just not WILLING to give up all the extras that losing a 2nd income entails)
The latest is that Mrs. WBill "shouldn't homeschool so that she doesn't lose her identity", whatever that means. And this is from my Mother in Law, who I would think would want the very best for her grandkid.
I'm very lucky in that my wife knows her own mind and is not afraid to tell them to get stuffed.
