I can see that your approach would be effective at shutting down conversation and stopping people from telling you their wild conspiracy theories.

I think that with my experience, I've had to recognize how fragile some of the most important incentives are. Like the safety that underpins trust. To have trust, it needs to be safe for people to be wrong. That means I often have to listen respectfully to views that I find abhorrent, in order to get to the point that I can share my own thoughts fully.
