This week I actually had to defend the scientific validity of "non-destruction" to a group of year 9s at my wife's school.
Seems a couple of the kid's mothers were "in tune with the earth's cycles" or similar nonsense.
As I was only a guest speaker, I broke one of the rules and called their mothers crackpots and imbeciles who should be locked away.
I
don't think they will invite me back.
BTW - If you want to test the doomsdayers commitment to their theories, simply offer to bet your house/car/children against theirs.
Haven't had a taker yet!
