I get what you are saying, bit i think there is a different reason for why there is no inquiry. It’s a similar situation beyond politics. When you feel certain you are right, why would you bother inquiring? I’ve encountered this in religious, political, and other realms. When i encounter people who are certain of their beliefs, it is usually a one directional conversation - them telling me. There is no inquiry into what i think or believe. When i encounter this i try to take the opportunity to listen for understanding knowing full well there will be no reciprocation. I don’t bother to try to change their mind - they aren’t open to other possibilities and most like have some answer for everything. It doesn’t matter if it is true or not. The point isn’t to win, it is to learn. I thank the person for their time and sharing and focus on trying to see their humanity through it all.
