But would you be stupid enough to argue that the moon is made of green
cheese with one of the astronauts that had been there? This troll
definitely would...

Would you suggest creating a new forum requiring a valid pilot
certificate number to participate?

Nawh, we can just create two new groups underneath
rec.aviation.piloting...
rec.aviation.piloting.wantabes
rec.aviation.piloting.neverbes

This troll would be in the latter, of course...
