To answer your question, I have often changed my mind in my life. Precisely because I’ve always engaged with opponents, had animated debates, and sometimes encompassed their point of view. I don’t understand how one can stay stuck on a demonstrably false information, and be so mean about it that you wouldn’t want it undemonstrated. But I feel like 10-20% of the Gen Z generation has the same problem dealing with their parents consuming fake news.
I don't think we lost, I think some people have cognative bias and feminism has been hijacked in recent years by "Social Marxists" and mutated the original cause. When a person build's their cognition on a false premise a dysfunctional cognitive bias is formed. The individual will need to grow out of it themself, but it's hard to do because it requires breaking a bit of ones ego and facing ones shadow.

I also find myself disagreeing with my father's politics often. I do compartmentalize it into a judgment of his political views, not my view on him as a person.
