I'm guessing you mean politics, but surely this is topic, person, time, and space dependent.

For example, I abhor talking about modern politics. If it’s election season and I’m being asked to cast a vote or take some other specific civic action, then I understand it’s my civic duty to understand the situation and make a decision accordingly and I do.

But if it’s March and there’s really nothing specific I can do as a result of this particular conversation, I would probably also be in your camp of the “unwilling”. I would much rather chat about something else, or nothing at all.

I'm also assuming you're referring to in-person communication. If it's online communication, all bets are off. It's unlikely you're having a linear conversation and these days you're probably not even talking to a person.
