Exactly - I started noticing prideful ignorance in the early 2010s. People around me made bad choices and would not be corrected. Their ignorance was just as valid as someone else's actual knowledge. That's when, strengthened by their own baseless pride, their shame disappeared. I'm not saying shame is good, but when it's the only thing keeping the deplorables in check, maybe a little of it helps.
It used to be that I'm general, horrible people realised they were horrible and at least went through the motions of being decent. They were like cockroaches scurrying for the shadows when you turned on the light. Now they're like a cat peeing on your bed - they pause long enough to lock eyes with you, then continue peeing.
Speaking optimistically, at least now we know exactly who they are.
Listening to other people, especially to women, is a skill. Don't spend silent time in a conversation waiting for your chance to speak or be smart or witty, stay quiet and really process what you're hearing. Imagine yourself in their situation. Accept that what they say is exactly how they feel.
The less time you spend talking, the more your conversational partner will tell you, and the more you will start to understand them, their lives, their goals, and their anxieties.
Knowing and understanding other peoples' experiences will help you not only make better decisions in your own life, but understand why other people act and think the way they do. You'll be less likely to snap-judge or make assumptions about others. And knowing more about your loved ones, co-workers, and neighbours will allow you to help them effectively if they need it.
And travel abroad as much as possible - listen to people from other countries and cultures. The human experience is wildly varied and endlessly fascinating.
