I had basically the same conversation with a woman at work, she a self-proclaimed pacifist.
I asked her is she would not defend her child against an attacker or rapist. She replied she could not live with herself if she hurt someone. I asked if she would allow me to adopt her child as she did not have enough intelligence to be a parent. We have not spoken since that conversation.
You are right: can’t fix stupid.
The more examples I hear, the more it confirms to me that the essence of liberalism is the attempt to affirm the lie of “I’m a good person”.
Nothing else, including common sense and reason, matter.
