Don’t bother. If they’re threatening you, deescalate it if possible. If that doesn’t work, defend yourself by any means necessary. Otherwise, stay away from them. It’s a waste of time, and they might snitch to the FIB.
I ignore their prattle, and ask them if they know the thrust of a single F-1 engine from the Saturn. I describe the inertial guidance system. I ask them if they know the second stage engines are the same ones used on the SLS, with a few updates of course. They usually go away.
